| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: L2CAP: use proto_lock for l2cap_data to fix l2cap_disconn_ind
hci_conn::l2cap_data is accessed without locks in l2cap_disconn_ind via
hci_conn_timeout (disc_work) -> hci_proto_disconn_ind ->
l2cap_disconn_ind. This is UAF if the l2cap_conn is deleted
concurrently.
disc_work is disabled sync in hci_conn_del(), so we cannot take
hci_dev_lock in disc_work.
Fix by using proto_lock to guard l2cap_data, in addition to hdev->lock
which is held in other access paths. |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/erdma: Hold CQ references when processing EQ events
EQ handlers look up CQs from dev->cq_xa and invoke CQ completion or
error callbacks outside the xarray lock. erdma_destroy_cq() can erase the
CQ from the xarray and free its queue buffer and doorbell record while a
previously scheduled EQ handler is still using the CQ.
Add a CQ refcount and take a reference under the xarray lock with
refcount_inc_not_zero(). Remove the CQ from the xarray before dropping
the destroy-path reference, then wait for in-flight EQ users before
releasing CQ resources. |
| Cotonti through 1.0.0 fails to validate anti-CSRF tokens in the contact plugin submission handler, allowing attackers to forge messages. Attackers can auto-submit contact forms from attacker-controlled pages to send forged messages attributed to authenticated victims to the administrator inbox. |
| The WP2Social Auto Publish plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 2.4.12 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled. |
| A vulnerability was identified in Pixelfed up to 0.12.11. Impacted is the function instancePeers of the file app/Http/Controllers/Api/ApiV1Controller.php of the component OAuth Scope Handler. Such manipulation of the argument ID leads to missing authentication. The attack may be performed from remote. The exploit is publicly available and might be used. Upgrading to version 0.12.10 is recommended to address this issue. The name of the patch is 68dca5097305fa0065d029587b2233524636025a. Upgrading the affected component is advised. |
| In the Linux kernel, the following vulnerability has been resolved:
inetpeer: randomize RB-tree node comparison using SipHash
The inetpeer rate limiting system stores peer entries in a Red-Black tree
keyed deterministically on the remote IP address. Because tree lookups walk
the RB-tree using standard lexicographical comparisons (inetpeer_addr_cmp),
an off-path adversary can predict the exact topology of the tree and the
sequence of nodes traversed during lookups (the gc_stack candidate list).
By combining deterministic tree traversal with aggressive garbage collection
(triggered when tree size exceeds inet_peer_threshold), an attacker can
selectively force the eviction of targeted inet_peer nodes. When an evicted
node is subsequently re-created upon receiving a new packet, its rate-limiting
token bucket (rate_tokens, rate_last) is reset to full capacity. This creates
a side-channel primitive allowing off-path attackers to bypass IP-keyed ICMP
rate limits and infer open UDP ports (similar to SAD DNS style attacks).
Mitigate this by randomizing the RB-tree node comparison logic using SipHash
with a secret key (inetpeer_hash_key) initialized via net_get_random_once().
Nodes are ordered in the tree by SipHash(addr, key) rather than raw IP
addresses. Because the secret key is unknown to external entities, the tree
layout and lookup traversal paths are unpredictable to off-path adversaries,
breaking the deterministic eviction gadget.
Cache the computed 64-bit SipHash (hash) in struct inet_peer and compute the
target hash (dhash) once at the beginning of inet_getpeer() to avoid recomputing
SipHash at every step of the RB-tree walk. |
| In the Linux kernel, the following vulnerability has been resolved:
ip6mr: do not clone dst in ip6mr_cache_report()
IPv6 input attaches a non-refcounted (NOREF) dst to skbs under RCU.
When an ingress multicast packet misses MFC lookup,
ip6mr_cache_unresolved() places the skb onto the unresolved queue,
escaping the receive-side RCU grace period.
If the underlying route is deleted and freed, and the MFC queue is later
resolved with a wrong parent interface, ip6_mr_forward() invokes
ip6mr_cache_report(..., MRT6MSG_WRONGMIF), which executes
dst_clone(skb_dst(pkt)) on the freed dst entry, triggering a slab
use-after-free.
Report packets queued to mroute6_sk (a raw socket) and netlink
notifications do not require an attached dst entry.
Fix this by:
1. Removing dst_clone() in ip6mr_cache_report() and ensuring report skbs
do not hold a dst.
2. Dropping skb_dst before queuing unresolved skbs in
ip6mr_cache_unresolved(), matching the fact that multicast
forwarding resolves outgoing routes anew via ip6_route_output(). |
| In the Linux kernel, the following vulnerability has been resolved:
net: bridge: Reject descending VLAN tunnel ranges
A pair of descending VLAN and tunnel IDs can pass the tunnel range span
check. The VLAN subtraction produces a negative int, which is converted
to unsigned when compared with the u32 tunnel ID subtraction. It can
therefore equal the wrapped tunnel ID delta.
The range loop then performs no iterations. Since the batched
notification handling added a post-loop error check, this leaves err
uninitialized and makes the request's return value unpredictable.
Reject descending VLAN ranges before comparing the spans. Valid
ascending and single-entry ranges remain unchanged, while malformed
descending ranges consistently return -EINVAL.
This issue was found by a static analysis checker and confirmed by
manual source review. |
| In the Linux kernel, the following vulnerability has been resolved:
irqchip/gic-v5: Check get_logical_index() return value in MADT IAFFID parsing
In gic_acpi_parse_iaffid() a given MADT GICC entry might not correspond
to a logical cpu recognized by the kernel, resulting in the cpu variable
initialization to an error value.
Currently, the get_logical_index() return value is not checked for failure,
which might result in out-of-bounds memory corruption while trying to
index a per_cpu variable array.
Add a check to evaluate get_logical_index() return value. |
| In the Linux kernel, the following vulnerability has been resolved:
irqchip/gic-v5: Clear per-CPU IRS data on teardown
IRS affinity setup publishes an IRS pointer and IAFFID state in the
per-CPU data before the remaining IRS initialization can fail. The
error path then frees the IRS data without clearing that published
state, leaving CPUs associated with freed memory.
On initialization failure and normal IRS teardown, clear the per-CPU
IRS association by removing the stale pointer to irs_data. Also
invalidate the per-CPU IAFFID state for any CPUs that were tied to the
IRS before it was freed. |
| In the Linux kernel, the following vulnerability has been resolved:
irqchip/renesas-rzg2l: Fix loss of interrupt
rzg2l_clear_irq_int() and rzg2l_clear_tint_int() perform a
read-modify-write on the ISCR/TSCR status registers to clear the bit
for the interrupt just handled. Since these registers are
write-0-to-clear per bit, this is racy:
If another interrupt's status bit gets set between the read and the write,
that bit is written back as 0 by the software-constructed value, clearing
an interrupt that hasn't been serviced yet and losing it.
This can be reproduced by triggering multiple interrupts at once, e.g.:
gpioset -c gpiochip0 355=0 353=0 328=0 352=0
Fix this by writing back only the bit being cleared, with all other bits
set to 1, instead of read-modify-writing the whole register. Since 1-bits
are left unchanged by hardware, concurrently-set status bits for other
interrupts are preserved. |
| In the Linux kernel, the following vulnerability has been resolved:
clk: devres: fix cleanup in devm_clk_get_optional_enabled_with_rate()
devm_clk_get_optional_enabled_with_rate() registers its cleanup action
before setting the clock rate. If setting the rate fails, it attempts to
disable and unprepare a clock that was never enabled. This issue was
spotted while reviewing "rust: clk: add devres-managed clks" [1].
Register the cleanup action only after successfully preparing and enabling
the clock.

| In the Linux kernel, the following vulnerability has been resolved:
ksmbd: scope session state changes to bound connections
ksmbd_all_conn_set_status() treats every connection whose transient
binding flag is set as belonging to the target SessionId. A logoff or
session replacement can consequently move an unrelated connection to
NEED_RECONNECT or NEED_SETUP.
Pass the target session itself and select connections using either the
connection-local session xarray or the session's permanent channel list.
Use the same association test while waiting for requests to drain.
Serialize session-wide status changes under request_lock and do not
overwrite EXITING or RELEASING. Protect the shutdown transition with the
same lock so a concurrent session update cannot revive a closing
connection. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Disallow bpf_{g,s}etsockopt() in cgroup UNIX getname hooks
_bpf_setsockopt() and _bpf_getsockopt() call sock_owned_by_me() for
full sockets, so these helpers expect the socket lock to be held.
BPF_CGROUP_UNIX_GETPEERNAME and BPF_CGROUP_UNIX_GETSOCKNAME run BPF
programs without acquiring the socket lock. A program attached to
either hook can therefore trigger the sock_owned_by_me() warning by
calling bpf_setsockopt() or bpf_getsockopt().
Disallow bpf_setsockopt() and bpf_getsockopt() for CGROUP_UNIX_GETPEERNAME
and CGROUP_UNIX_GETSOCKNAME. |
| In the Linux kernel, the following vulnerability has been resolved:
erofs: fix interlaced ztailpacking pclusters
On-disk sizes of interlaced pclusters should be block-aligned, and
ztailpacking interlaced pclusters should be invalid at all.
Currently, mkfs.erofs won't generate any interlaced pcluster with
ztailpacking enabled, so this doesn't affect any existing valid
filesystems.
However, crafted images can contain invalid interlaced ztailpacking
pclusters, resulting in an out-of-bounds read from a kmap'd page and
copying irrelevant kernel memory into userspace-visible page cache. |
| In the Linux kernel, the following vulnerability has been resolved:
ksmbd: serialize oplock close with pending break ownership
close may abort an in-flight oplock break while another breaker already
holds an opinfo reference. Releasing pending_break wakes that waiter, but
without serializing the close transition with bit acquisition it can become
a new break owner through the test_and_set_bit() fast path. It can then
overwrite OPLOCK_CLOSING with OPLOCK_ACK_WAIT and continue a break for
a dying opinfo.
Make OPLOCK_CLOSING terminal once the opinfo is removed from the inode
list. Serialize that transition, pending_break acquisition, and
OPLOCK_ACK_WAIT setup with an opinfo state lock. A breaker which loses
the race releases its ownership and returns -ENOENT. Explicitly wake
pending_break waiters during close so they can observe the terminal state.
Also prevent ACK and timeout paths from replacing OPLOCK_CLOSING with
OPLOCK_STATE_NONE. |
| In the Linux kernel, the following vulnerability has been resolved:
ksmbd: free preauth sessions on connection teardown
SMB3.1.1 multichannel binding preserves the preauthentication hash in a
preauth_session between the NTLM negotiate and authenticate requests.
The binding NTLM negotiate allocates this object and returns
STATUS_MORE_PROCESSING_REQUIRED. If the client disconnects before it sends
the authenticate request, neither the authenticate nor error cleanup paths
free the object.
Release any remaining preauthentication sessions when tearing down the
connection. Initialize the list when allocating the connection so that this
cleanup is safe regardless of the negotiated dialect. |

Fix the invalid memory access by validating the DMA index read from the
hardware before it is used as a queue index. An out-of-range value, such
as the 0xFFFFFFFF returned while the bus is hung, is now clamped so it can
no longer corrupt q->head or q->tail. In addition, check the bus_hung flag
in mt7921_mac_reset_work() before attempting the reset sequence, reject MCU
messages while the bus is hung, and install no-op bus operations when an
unrecoverable AER error is detected, preventing further invalid hardware
accesses.
Due to hardware limitations - such as the lack of a connected hardware
reset pin or the absence of host re-probe functionality - affected Wi-Fi
devices may not fully recover to a normal operational state after
certain errors, even with AER enabled. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu/pm/powerplay: bounds-check voltage index in Vega10 lookup
vddInd, vddciInd and mvddInd from VBIOS-parsed tables index into vddc,
vddci and vddmem lookup tables without bounds checks across nine sites.
Return -EINVAL when any index is out of range. |
| Suricata before 8.0.7 has a DoH2 type confusion that can cause an invalid free, because cleanup code for the HTTP2 state is executed even though the actual state is HTTP1 (when there is a DoH2 request with an HTTP1 to HTTP2 upgrade). This requires app-layer.protocols.doh2 to be enabled, which is the default in 8.x versions. |
