CVSS v3.1 |
| The Ultimate Addons for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Navigation Menu Widget data-toggle-icon/data-close-icon Attributes in all versions up to, and including, 2.9.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. wp_kses_post, applied on save for users without unfiltered_html, does not neutralize HTML-entity-encoded payloads stored inside data-* attributes on kses-allowed elements, as the browser decodes these values client-side before jQuery .html() renders them as markup. |
| SolarWinds Serv-U is affected by an insecure direct object reference (IDOR) vulnerability that can lead to remote code execution. Domain administrator access is required. The impact is lower in Windows deployments. |
| A flaw was found in the sbc library (BlueZ SBC codec). An off-by-one error in the SBC frame decoder allows a crafted audio payload to trigger a one-byte heap out-of-bounds read. This could allow an adjacent attacker streaming Bluetooth audio to read a single byte of adjacent heap memory. |
| A flaw was found in the Visual Studio Code Ansible Lightspeed extension. This command injection vulnerability (CWE-78) arises from improper handling of the ansible.executionEnvironment.containerOptions and ansible.executionEnvironment.volumeMounts settings, allowing an attacker to inject shell separators. This can be triggered automatically during Language Server initialization or manually when executing a playbook. Successful exploitation leads to remote code execution (RCE) on the victim's machine with the privileges of the Visual Studio Code user, potentially resulting in a complete system compromise. |
| The issue is unexpected program termination based on ordering and/or specific content in responses to queries for CNAME or DNAME, and A records. Specifically, if a client queries for a DNAME and A record below the DNAME to the resolver, and the authoritative server responds positively to the A query but delays the DNAME response and later responds negatively, `named` may quit unexpectedly. Or, if a client queries for a CNAME and A record for the same name to the resolver, and the authoritative server responds positively to the A query but delays the CNAME response and later responds with a self-referential CNAME, the same failure may occur.
This issue affects BIND 9 versions 9.18.0 through 9.18.50, 9.20.0 through 9.20.24, 9.18.11-S1 through 9.18.50-S1, and 9.20.9-S1 through 9.20.24-S1. |
| Dell PowerProtect Data Manager, versions prior to 20.2.0.0, contain(s) an Improper Input Validation vulnerability in the REST API. A high privileged attacker with remote access could potentially exploit this vulnerability, leading to Remote execution. |
| SolarWinds Serv-U is affected by a privilege escalation vulnerability that allows a domain user group to be elevated into an administrator group. The impact is lower in Windows deployments. |
| BIND may accept incorrect child-zone NSEC3 records as valid, which could allow an attacker to forge authenticated NXDOMAIN responses.
This issue affects BIND 9 versions 9.18.0 through 9.18.50, 9.20.0 through 9.20.24, 9.21.0 through 9.21.23, 9.11.3-S1 through 9.18.50-S1, and 9.20.9-S1 through 9.20.24-S1. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/gem: fix race between change_handle and handle_delete
drm_gem_change_handle_ioctl leaves the old handle live in the IDR
during the window between spin_unlock(table_lock) and the final
spin_lock(table_lock). A concurrent drm_gem_handle_delete on the old
handle succeeds in this window, decrements handle_count to 0, and frees
the GEM object while the new handle's IDR entry still references it.
NULL the old handle's IDR entry before dropping table_lock so that any
concurrent GEM_CLOSE on the old handle sees NULL and returns -EINVAL.
Restore the old entry on the prime-bookkeeping error path. |
| In the Linux kernel, the following vulnerability has been resolved:
scsi: target: iscsi: Fix CRC overread and double-free in iscsit_handle_text_cmd()
Two latent bugs in the Text-phase handler, both present since the
original LIO integration in commit e48354ce078c ("iscsi-target: Add
iSCSI fabric support for target v4.1"):
1) DataDigest CRC buffer overread (4 bytes past text_in).
text_in is kzalloc()'d at ALIGN(payload_length, 4). rx_size is then
incremented by ISCSI_CRC_LEN to make room for the received DataDigest
in the iovec, but the same (now-bumped) rx_size is passed as the
buffer length to iscsit_crc_buf():
if (conn->conn_ops->DataDigest) {
...
rx_size += ISCSI_CRC_LEN;
}
...
if (conn->conn_ops->DataDigest) {
data_crc = iscsit_crc_buf(text_in, rx_size, 0, NULL);
iscsit_crc_buf() walks rx_size bytes of text_in with crc32c(), so
when DataDigest is negotiated it reads 4 bytes past the end of the
text_in allocation. KASAN reproduces this directly on the unpatched
mainline tree as slab-out-of-bounds in crc32c() called from the Text
PDU path. The OOB bytes feed crc32c() and are then compared against
the initiator-supplied checksum, so the value does not flow back to
the attacker, but the kernel does read past the buffer on every Text
PDU with DataDigest=CRC32C.
Fix by passing the actual padded payload length
(ALIGN(payload_length, 4)) that was used for the kzalloc().
2) Stale cmd->text_in_ptr re-free (double-free) on ERL>0 bad DataDigest
drop.
On DataDigest mismatch with ErrorRecoveryLevel > 0 the handler
silently drops the PDU and lets the initiator plug the CmdSN gap:
kfree(text_in);
return 0;
cmd->text_in_ptr still points at the freed buffer. The next Text
Request on the same ITT re-enters iscsit_setup_text_cmd(), which
unconditionally does
kfree(cmd->text_in_ptr);
cmd->text_in_ptr = NULL;
freeing the same pointer a second time. Session teardown via
iscsit_release_cmd() has the same shape and hits the same double-free
if the connection is dropped before a second Text Request arrives.
On an unmodified mainline tree the bug-1 CRC overread fires first on
the initial valid Text Request and perturbs the subsequent state, so
#4 was isolated by building a kernel with only the bug-1 hunk of this
patch applied plus temporary printk() observability around the three
relevant kfree() sites. The observability prints are not part of
this patch. On that build, a three-PDU Text Request sequence after
login produces two back-to-back splats:
BUG: KASAN: double-free in iscsit_setup_text_cmd+0x??
BUG: KASAN: double-free in iscsit_release_cmd+0x??
showing the same pointer freed in the ERL>0 drop path and again in
iscsit_setup_text_cmd() (next Text Request on the same ITT) and once
more in iscsit_release_cmd() (session teardown). On distro kernels
with CONFIG_SLAB_FREELIST_HARDENED=y (default) the double-free
becomes a remote kernel BUG(); on non-hardened kernels it corrupts
the slab freelist.
Fix by clearing cmd->text_in_ptr after the kfree() in the ERL>0 drop
path. With both hunks applied #4 is directly observable on the stock
tree without observability printks; fixing bug-1 alone would mask #4
less, not more, so the hunks are submitted together.
Both fixes are one-liners. The Text PDU state machine is unchanged and
the wire protocol is unaffected. |
| In the Linux kernel, the following vulnerability has been resolved:
scsi: fcoe: Reject FIP descriptors with zero fip_dlen in CVL walker
drivers/scsi/fcoe/fcoe_ctlr.c::fcoe_ctlr_recv_clr_vlink() advanced the
descriptor cursor by an attacker-supplied fip_dlen without ever
requiring dlen >= sizeof(struct fip_desc) in the default branch. The
named descriptor cases (FIP_DT_MAC, FIP_DT_NAME, FIP_DT_VN_ID) checked
their per-type minimum lengths, but a FIP_DT_NON_CRITICAL descriptor
(fip_dtype >= 128, which the standard requires receivers to silently
ignore) skipped that check entirely.
An unauthenticated L2 peer on the FCoE control VLAN could hang
fcoe_ctlr_recv_work on an fcoe, qedf, or bnx2fc initiator indefinitely
by emitting one FIP CVL frame whose single descriptor had fip_dtype ==
FIP_DT_NON_CRITICAL and fip_dlen == 0: the cursor advanced zero bytes
per iteration and the loop condition rlen >= sizeof(*desc) stayed true
forever, blocking every subsequent FIP frame on that controller.
Tighten the outer dlen guard to also reject dlen < sizeof(struct
fip_desc), so a malformed descriptor whose length cannot even cover the
descriptor header is rejected before the switch. This is the same
lower-bound the named cases already apply and is the minimum scope that
closes the loop. |
| In the Linux kernel, the following vulnerability has been resolved:
thunderbolt: property: Reject dir_len < 4 to prevent size_t underflow
On the non-root path, __tb_property_parse_dir() takes dir_len from
entry->length (u16 widened to size_t). Two distinct OOB conditions
follow when entry->length < 4:
1. The non-root path begins with kmemdup(&block[dir_offset],
sizeof(*dir->uuid), ...) which always reads 4 dwords from
dir_offset. tb_property_entry_valid() only enforces
dir_offset + entry->length <= block_len, so a crafted entry
with dir_offset close to the end of the property block and
entry->length in 0..3 passes that gate but lets the UUID copy
run off the block (e.g. dir_offset = 497, dir_len = 3 in a
500-dword block reads block[497..501]).
2. After the kmemdup, content_len = dir_len - 4 underflows size_t
to ~SIZE_MAX, nentries becomes SIZE_MAX / 4, and the entry
walk runs OOB on each iteration until an entry fails
validation or the kernel oopses on an unmapped page.
Reject dir_len < 4 on the non-root path *before* the UUID kmemdup,
which closes both holes.
Also move INIT_LIST_HEAD(&dir->properties) up to immediately after
the dir allocation so the new error-return path (and the existing
uuid-alloc failure path) calling tb_property_free_dir() sees a
walkable list rather than the zero-initialized NULL next/prev that
list_for_each_entry_safe() would oops on. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: f_fs: copy only received bytes on short ep0 read
ffs_ep0_read() allocates its control-OUT data buffer with
kmalloc() (not kzalloc) at the Length value from the Setup
packet, then copies that full len to userspace regardless of
how many bytes were actually received:
data = kmalloc(len, GFP_KERNEL);
...
ret = __ffs_ep0_queue_wait(ffs, data, len);
if ((ret > 0) && (copy_to_user(buf, data, len)))
ret = -EFAULT;
__ffs_ep0_queue_wait() returns req->actual, which on a short
control OUT transfer is strictly less than len. The
copy_to_user() call still copies len bytes, so on a short OUT
the last (len - ret) bytes of the kmalloc() buffer --
uninitialised slab residue -- are delivered to the FunctionFS
daemon.
Short ep0 OUT completions are specified USB control-transfer
behavior and are produced by in-tree UDCs:
* dwc2 continues on req->actual < req->length for ep0 DATA OUT
(short-not-ok is the only ep0-OUT stall path).
* aspeed_udc ends ep0 OUT on rx_len < ep->ep.maxpacket.
* renesas_usbf logs "ep0 short packet" and completes the
request.
* dwc3 stalls on short IN but not on short OUT.
A short ep0 OUT is therefore not evidence of a broken UDC; it is
a normal condition f_fs has to cope with. The sibling gadgetfs
implementation in drivers/usb/gadget/legacy/inode.c already does
this correctly via min(len, dev->req->actual) before
copy_to_user(). This patch brings f_fs.c to the same safe
pattern rather than trimming at a defensive layer.
The bug is reached from the FunctionFS device node, which in
real deployments is owned by the privileged gadget daemon
(adbd, UMS, composite gadget services, etc.); it is not
reachable from unprivileged userspace. Linux host stacks
normally reject short-wLength control OUTs before they reach
the gadget, so reproducing this required a build that
bypasses that host-side check. With the bypass in place, a
1-byte payload on a 64-byte Setup produces 63 bytes of
non-canary slab residue in the daemon's read buffer.
Fix by copying only ret (actually received) bytes to
userspace. |
| In the Linux kernel, the following vulnerability has been resolved:
USB: serial: mct_u232: fix memory corruption with small endpoint
The driver overrides the maximum transfer size for a specific device
which only accepts 16 byte packets for its 32 byte bulk-out endpoint.
Make sure to never increase the maximum transfer size to prevent slab
corruption should a malicious device report a smaller endpoint max
packet size than expected. |
| In the Linux kernel, the following vulnerability has been resolved:
USB: serial: keyspan: fix missing indat transfer sanity check
Add the missing sanity check on the size of usa49wg indat transfers to
avoid parsing stale or uninitialised slab data. |
| In the Linux kernel, the following vulnerability has been resolved:
USB: serial: belkin_sa: validate interrupt status length
The Belkin interrupt callback treats interrupt data as a four-byte
status report and reads LSR/MSR fields at offsets 2 and 3. The
interrupt-in buffer length is derived from endpoint wMaxPacketSize, and
short interrupt transfers may complete successfully with a smaller
actual_length.
Check the completed interrupt packet length before parsing status
fields so short interrupt endpoints and short successful packets are
ignored instead of causing out-of-bounds or stale status-byte reads.
KASAN report as below:

usbip: vudc: Fix use after free bug in vudc_remove due to race condition
This patch follows up Zheng Wang's 2023 report of a use-after-free in
vudc_remove(). The original thread stalled on Shuah Khan's request for
runtime testing of the unplug/unbind path. This patch supplies that
testing and keeps Zheng's original fix shape.
In vudc_probe(), v_init_timer() binds udc->tr_timer.timer to v_timer().
usbip_sockfd_store() starts the timer via v_start_timer()/v_kick_timer().
vudc_remove() can then free the containing struct vudc while the timer is
still pending or executing.
KASAN confirms the race on an unpatched x86_64 QEMU guest with
CONFIG_KASAN=y, CONFIG_USBIP_VUDC=y, CONFIG_USB_ZERO=y, and a tight loop
that repeatedly writes a socket fd to usbip_sockfd, closes the socket
pair, and unbinds/rebinds usbip-vudc.0:
BUG: KASAN: slab-use-after-free in __run_timer_base.part.0+0x8ba/0x8e0
Write of size 8 at addr ffff888001b80740 by task trigger_and_unb/239
Allocated by task 239:
vudc_probe+0x4d/0xaa0
Freed by task 239:
kfree+0x18f/0x520
device_release_driver_internal+0x388/0x540
unbind_store+0xd9/0x100
This lands in the timer core rather than v_timer() itself because the
embedded timer_list is being walked after its containing struct vudc has
already been freed. The underlying lifetime bug is the same one Zheng
reported.
With v_stop_timer() called from vudc_remove() and the timer deleted
synchronously, the same harness completed 5000 bind/unbind iterations
with no KASAN report. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: musb: omap2430: Fix use-after-free in omap2430_probe()
In omap2430_probe(), of_node_put(np) is called prematurely before the
last access to np, leading to a use-after-free if the node's reference
count drops to zero. Move the of_node_put() calls after the last use of
np in both the success and error paths. |

Input: atmel_mxt_ts - fix boundary check in mxt_prepare_cfg_mem
When a configuration file provides an object size that is larger than the
driver's known mxt_obj_size(object), the driver intends to discard the
extra bytes.
The loop iterates using for (i = 0; i < size; i++). Inside the loop, the
condition to skip processing extra bytes is:
if (i > mxt_obj_size(object))
continue;
Since i is a 0-based index, the valid indices for the object are 0 through
mxt_obj_size(object) - 1.
When i == mxt_obj_size(object), the condition evaluates to false, and the
code processes the byte instead of discarding it.
This causes the code to calculate byte_offset = reg + i - cfg->start_ofs
and writes the byte there, overwriting exactly one byte of the adjacent
instance or object.
Update the boundary check to skip extra bytes correctly by using >=. |
| In the Linux kernel, the following vulnerability has been resolved:
dma-buf: fix UAF in dma_buf_fd() tracepoint
Once FD_ADD() returns, the fd is live in the file descriptor table
and a thread sharing that table can close() it before DMA_BUF_TRACE()
runs. The close drops the last reference, __fput() frees the dma_buf,
and the tracepoint then dereferences dmabuf to take dmabuf->name_lock
-- slab-use-after-free.
Split FD_ADD() back into get_unused_fd_flags() + fd_install() and
emit the tracepoint between them. While the fdtable slot is reserved
with a NULL file pointer, a racing close() returns -EBADF without
entering __fput(), so the dma_buf stays alive across the trace. Same
approach as commit 2d76319c4cbb ("dma-buf: fix UAF in dma_buf_put()
tracepoint").
This undoes the FD_ADD() conversion done in commit 34dfce523c90
("dma: convert dma_buf_fd() to FD_ADD()"); FD_ADD() has no place to
hook the tracepoint safely. |
