CVSS v3.1 |
| GitBucket 4.23.1 contains an unauthenticated remote code execution vulnerability that allows attackers to execute arbitrary commands by exploiting weak secret token generation and insecure file upload functionality. Attackers can brute-force the Blowfish encryption key, upload a malicious JAR plugin via the git-lfs endpoint, and execute system commands through an exposed exploit endpoint. |
| Home Assistant Community Store (HACS) prior to 1.10.0 contains a path traversal vulnerability that allows unauthenticated attackers to read sensitive files by traversing directories via the /hacsfiles/ endpoint. Attackers can retrieve the .storage/auth file containing user credentials and refresh tokens, then craft valid JWT tokens to gain administrative access to Home Assistant instances. |
| Nx Console is the user interface for Nx & Lerna. On 19 May 2026, a malicious version of Nx Console, 18.95.0, was published at 12:30 PM UTC and removed soon after at 12:48 PM UTC, leaving it available for ~18 minutes in Visual Studio Marketplace. For OpenVSX, the problem was detected later, and the compromised version was available from 12:33 UTC to 13:09 UTC (~36 minutes). Version 18.100.0 of Nx Console is not compromised and users may remediate by upgrading to that version. |
| Hedera Guardian through 3.5.1 contains an authentication bypass vulnerability in the GET /api/v1/demo/registered-users endpoint that allows unauthenticated attackers to retrieve sensitive user information. Attackers can access the endpoint without providing authentication credentials to obtain usernames, Hedera DIDs, parent registry DIDs, system roles, and policy role assignments for all registered users in the system. |
| CWE-312: Cleartext Storage of Sensitive Information vulnerability exists that could cause the disclosure of a sensitive information which could result in revealing protected source code and loss of confidentiality, When an authorized attacker accesses the source code for editing or compiling it. |
| In the Linux kernel, the following vulnerability has been resolved:
hwmon: (powerz) Avoid cacheline sharing for DMA buffer
Depending on the architecture the transfer buffer may share a cacheline
with the following mutex. As the buffer may be used for DMA, that is
problematic.
Use the high-level DMA helpers to make sure that cacheline sharing can
not happen.
Also drop the comment, as the helpers are documentation enough.

| In the Linux kernel, the following vulnerability has been resolved:
rxrpc: Fix memory leaks in rxkad_verify_response()
Fix rxkad_verify_response() to free the ticket and the server key under all
circumstances by initialising the ticket pointer to NULL and then making
all paths through the function after the first allocation has been done go
through a single common epilogue that just releases everything - where all
the releases skip on a NULL pointer. |
| In the Linux kernel, the following vulnerability has been resolved:
dm mirror: fix integer overflow in create_dirty_log()
The argument count calculation in create_dirty_log() performs
`*args_used = 2 + param_count` before validating against argc. When a
user provides a param_count close to UINT_MAX via the device mapper
table string, this unsigned addition wraps around to a small value,
causing the subsequent `argc < *args_used` check to be bypassed.
The overflowed param_count is then passed as argc to dm_dirty_log_create(),
where it can cause out-of-bounds reads on the argv array.
Fix by comparing param_count against argc - 2 before performing the
addition, following the same pattern used by parse_features() in the
same file. Since argc >= 2 is already guaranteed, the subtraction is
safe. |
| In the Linux kernel, the following vulnerability has been resolved:
libceph: Prevent potential null-ptr-deref in ceph_handle_auth_reply()
If a message of type CEPH_MSG_AUTH_REPLY contains a zero value for both
protocol and result, this is currently not treated as an error. In case
of ac->negotiating == true and ac->protocol > 0, this leads to setting
ac->protocol = 0 and ac->ops = NULL. Thereafter, the check for
ac->protocol != protocol returns false, and init_protocol() is not
called. Subsequently, ac->ops->handle_reply() is called, which leads to
a null pointer dereference, because ac->ops is still NULL.
This patch changes the check for ac->protocol != protocol to
!ac->protocol, as this also includes the case when the protocol was set
to zero in the message. This causes the message to be treated as
containing a bad auth protocol. |
| In the Linux kernel, the following vulnerability has been resolved:
EDAC/versalnet: Fix device_node leak in mc_probe()
of_parse_phandle() returns a device_node reference that must be released with
of_node_put(). The original code never freed r5_core_node on any exit path,
causing a memory leak.
Fix this by using the automatic cleanup attribute __free(device_node) which
ensures of_node_put() is called when the variable goes out of scope. |
| In the Linux kernel, the following vulnerability has been resolved:
KVM: nSVM: Triple fault if restore host CR3 fails on nested #VMEXIT
If loading L1's CR3 fails on a nested #VMEXIT, nested_svm_vmexit()
returns an error code that is ignored by most callers, and continues to
run L1 with corrupted state. A sane recovery is not possible in this
case, and HW behavior is to cause a shutdown. Inject a triple fault
instead, and do not return early from nested_svm_vmexit(). Continue
cleaning up the vCPU state (e.g. clear pending exceptions), to handle
the failure as gracefully as possible.
From the APM:
Upon #VMEXIT, the processor performs the following actions in order to
return to the host execution context:
...
if (illegal host state loaded, or exception while loading host state)
shutdown
else
execute first host instruction following the VMRUN
Remove the return value of nested_svm_vmexit(), which is mostly
unchecked anyway. |
| In the Linux kernel, the following vulnerability has been resolved:
crypto: authencesn - reject short ahash digests during instance creation
authencesn requires either a zero authsize or an authsize of at least
4 bytes because the ESN encrypt/decrypt paths always move 4 bytes of
high-order sequence number data at the end of the authenticated data.
While crypto_authenc_esn_setauthsize() already rejects explicit
non-zero authsizes in the range 1..3, crypto_authenc_esn_create()
still copied auth->digestsize into inst->alg.maxauthsize without
validating it. The AEAD core then initialized the tfm's default
authsize from that value.
As a result, selecting an ahash with digest size 1..3, such as
cbcmac(cipher_null), exposed authencesn instances whose default
authsize was invalid even though setauthsize() would have rejected the
same value. AF_ALG could then trigger the ESN tail handling with a
too-short tag and hit an out-of-bounds access.
Reject authencesn instances whose ahash digest size is in the invalid
non-zero range 1..3 so that no tfm can inherit an unsupported default
authsize. |
| In the Linux kernel, the following vulnerability has been resolved:
mm/page_alloc: return NULL early from alloc_frozen_pages_nolock() in NMI on UP
On UP kernels (!CONFIG_SMP), spin_trylock() is a no-op that
unconditionally succeeds even when the lock is already held. As a
result, alloc_frozen_pages_nolock() called from NMI context can
re-enter rmqueue() and acquire the zone lock that the interrupted
context is already holding, corrupting the freelists.
With CONFIG_DEBUG_SPINLOCK on UP, the following BUG is triggered with
the slub_kunit test module:
BUG: spinlock trylock failure on UP on CPU#0, kunit_try_catch/243
[...]

Fix this by returning NULL early when invoked from NMI on a UP kernel. |
| In the Linux kernel, the following vulnerability has been resolved:
vfio/cdx: Serialize VFIO_DEVICE_SET_IRQS with a per-device mutex
vfio_cdx_set_msi_trigger() reads vdev->config_msi and operates on the
vdev->cdx_irqs array based on its value, but provides no serialization
against concurrent VFIO_DEVICE_SET_IRQS ioctls. Two callers can race
such that one observes config_msi as set while another clears it and
frees cdx_irqs via vfio_cdx_msi_disable(), resulting in a use-after-free
of the cdx_irqs array.
Add a cdx_irqs_lock mutex to struct vfio_cdx_device and acquire it in
vfio_cdx_set_msi_trigger(), which is the single chokepoint through
which all updates to config_msi, cdx_irqs, and msi_count flow, covering
both the ioctl path and the close-device cleanup path. This keeps the
test of config_msi atomic with the subsequent enable, disable, or
trigger operations.
Drop the pre-call !cdx_irqs test from vfio_cdx_irqs_cleanup() as part
of this change: the optimization it provided is redundant with the
!config_msi early-return inside vfio_cdx_msi_disable(), and leaving the
test in place would be an unsynchronized read of state the new lock is
meant to protect. |
| In the Linux kernel, the following vulnerability has been resolved:
rxgk: Fix potential integer overflow in length check
Fix potential integer overflow in rxgk_extract_token() when checking the
length of the ticket. Rather than rounding up the value to be tested
(which might overflow), round down the size of the available data. |

inotify: fix watch count leak when fsnotify_add_inode_mark_locked() fails
When fsnotify_add_inode_mark_locked() fails in inotify_new_watch(),
the error path calls inotify_remove_from_idr() but does not call
dec_inotify_watches() to undo the preceding inc_inotify_watches().
This leaks a watch count, and repeated failures can exhaust the
max_user_watches limit with -ENOSPC even when no watches are active.
Prior to commit 1cce1eea0aff ("inotify: Convert to using per-namespace
limits"), the watch count was incremented after fsnotify_add_mark_locked()
succeeded, so this path was not affected. The conversion moved
inc_inotify_watches() before the mark insertion without adding the
corresponding rollback.
Add the missing dec_inotify_watches() call in the error path. |
| In the Linux kernel, the following vulnerability has been resolved:
greybus: gb-beagleplay: fix sleep in atomic context in hdlc_tx_frames()
hdlc_append() calls usleep_range() to wait for circular buffer space,
but it is called with tx_producer_lock (a spinlock) held via
hdlc_tx_frames() -> hdlc_append_tx_frame()/hdlc_append_tx_u8()/etc.
Sleeping while holding a spinlock is illegal and can trigger
"BUG: scheduling while atomic".
Fix this by moving the buffer-space wait out of hdlc_append() and into
hdlc_tx_frames(), before the spinlock is acquired. The new flow:
1. Pre-calculate the worst-case encoded frame length.
2. Wait (with sleep) outside the lock until enough space is available,
kicking the TX consumer work to drain the buffer.
3. Acquire the spinlock, re-verify space, and write the entire frame
atomically.
This ensures that sleeping only happens without any lock held, and
that frames are either fully enqueued or not written at all.
This bug is found by CodeQL static analysis tool (interprocedural
sleep-in-atomic query) and my code review. |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/rxe: Validate pad and ICRC before payload_size() in rxe_rcv
rxe_rcv() currently checks only that the incoming packet is at least
header_size(pkt) bytes long before payload_size() is used.
However, payload_size() subtracts both the attacker-controlled BTH pad
field and RXE_ICRC_SIZE from pkt->paylen:
payload_size = pkt->paylen - offset[RXE_PAYLOAD] - bth_pad(pkt)
- RXE_ICRC_SIZE
This means a short packet can still make payload_size() underflow even
if it includes enough bytes for the fixed headers. Simply requiring
header_size(pkt) + RXE_ICRC_SIZE is not sufficient either, because a
packet with a forged non-zero BTH pad can still leave payload_size()
negative and pass an underflowed value to later receive-path users.
Fix this by validating pkt->paylen against the full minimum length
required by payload_size(): header_size(pkt) + bth_pad(pkt) +
RXE_ICRC_SIZE. |
| In the Linux kernel, the following vulnerability has been resolved:
md/md-llbitmap: skip reading rdevs that are not in_sync
When reading bitmap pages from member disks, the code iterates through
all rdevs and attempts to read from the first available one. However,
it only checks for raid_disk assignment and Faulty flag, missing the
In_sync flag check.
This can cause bitmap data to be read from spare disks that are still
being rebuilt and don't have valid bitmap information yet. Reading
stale or uninitialized bitmap data from such disks can lead to
incorrect dirty bit tracking, potentially causing data corruption
during recovery or normal operation.
Add the In_sync flag check to ensure bitmap pages are only read from
fully synchronized member disks that have valid bitmap data. |
| In the Linux kernel, the following vulnerability has been resolved:
ext4: fix missing brelse() in ext4_xattr_inode_dec_ref_all()
The commit c8e008b60492 ("ext4: ignore xattrs past end")
introduced a refcount leak in when block_csum is false.
ext4_xattr_inode_dec_ref_all() calls ext4_get_inode_loc() to
get iloc.bh, but never releases it with brelse(). |
