| OpenClaw before 2026.4.23 caches resolved webhook route secrets backed by SecretRef values, allowing stale secrets to remain valid after rotation and reload. Attackers with previously valid webhook route secrets can continue authenticating requests and invoking configured webhook task flows until gateway or plugin restart. |
| In the Linux kernel, the following vulnerability has been resolved:
dm array: fix releasing a faulty array block twice in dm_array_cursor_end
When dm_bm_read_lock() fails due to locking or checksum errors, it
releases the faulty block implicitly while leaving an invalid output
pointer behind. The caller of dm_bm_read_lock() should not operate on
this invalid dm_block pointer, or it will lead to undefined result.
For example, the dm_array_cursor incorrectly caches the invalid pointer
on reading a faulty array block, causing a double release in
dm_array_cursor_end(), then hitting the BUG_ON in dm-bufio cache_put().
Reproduce steps:
1. initialize a cache device
dmsetup create cmeta --table "0 8192 linear /dev/sdc 0"
dmsetup create cdata --table "0 65536 linear /dev/sdc 8192"
dmsetup create corig --table "0 524288 linear /dev/sdc $262144"
dd if=/dev/zero of=/dev/mapper/cmeta bs=4k count=1
dmsetup create cache --table "0 524288 cache /dev/mapper/cmeta \
/dev/mapper/cdata /dev/mapper/corig 128 2 metadata2 writethrough smq 0"
2. wipe the second array block offline
dmsteup remove cache cmeta cdata corig
mapping_root=$(dd if=/dev/sdc bs=1c count=8 skip=192 \
2>/dev/null | hexdump -e '1/8 "%u\n"')
ablock=$(dd if=/dev/sdc bs=1c count=8 skip=$((4096*mapping_root+2056)) \
2>/dev/null | hexdump -e '1/8 "%u\n"')
dd if=/dev/zero of=/dev/sdc bs=4k count=1 seek=$ablock
3. try reopen the cache device
dmsetup create cmeta --table "0 8192 linear /dev/sdc 0"
dmsetup create cdata --table "0 65536 linear /dev/sdc 8192"
dmsetup create corig --table "0 524288 linear /dev/sdc $262144"
dmsetup create cache --table "0 524288 cache /dev/mapper/cmeta \
/dev/mapper/cdata /dev/mapper/corig 128 2 metadata2 writethrough smq 0"

kernel BUG at drivers/md/dm-bufio.c:638!
Fix by setting the cached block pointer to NULL on errors.
In addition to the reproducer described above, this fix can be
verified using the "array_cursor/damaged" test in dm-unit:
dm-unit run /pdata/array_cursor/damaged --kernel-dir <KERNEL_DIR> |
| In the Linux kernel, the following vulnerability has been resolved:
ACPI: battery: Fix possible crash when unregistering a battery hook
When a battery hook returns an error when adding a new battery, then
the battery hook is automatically unregistered.
However the battery hook provider cannot know that, so it will later
call battery_hook_unregister() on the already unregistered battery
hook, resulting in a crash.
Fix this by using the list head to mark already unregistered battery
hooks as already being unregistered so that they can be ignored by
battery_hook_unregister(). |
| Apache::Session versions through 1.94 for Perl re-creates deleted sessions.
The session stores Apache::Session::Store::File and Apache::Session::Store::DB_File will create a session that does not exist. This can lead to sessions being revived, potentially with data that was to be deleted. |
| OpenClaw before 2026.4.15 captures resolved bearer-auth configuration at startup, allowing revoked tokens to remain valid after SecretRef rotation. Gateway HTTP and WebSocket handlers fail to re-resolve authentication per-request, enabling attackers to use rotated-out bearer tokens for unauthorized gateway access. |
| This issue was addressed through improved state management. This issue is fixed in iOS 18.5 and iPadOS 18.5. Muting the microphone during a FaceTime call may not result in audio being silenced. |
| An invalid memory address dereference was discovered in load_pnm in frompnm.c in libsixel before 1.8.3. |
| The nfs4_proc_lock function in fs/nfs/nfs4proc.c in the NFSv4 client in the Linux kernel before 2.6.31-rc4 allows remote NFS servers to cause a denial of service (NULL pointer dereference and panic) by sending a certain response containing incorrect file attributes, which trigger attempted use of an open file that lacks NFSv4 state. |
| Use-after-free vulnerability in the fasync_helper function in fs/fcntl.c in the Linux kernel before 2.6.33-rc4-git1 allows local users to gain privileges via vectors that include enabling O_ASYNC (aka FASYNC or FIOASYNC) on a locked file, and then closing this file. |
| Multiple race conditions in fs/pipe.c in the Linux kernel before 2.6.32-rc6 allow local users to cause a denial of service (NULL pointer dereference and system crash) or gain privileges by attempting to open an anonymous pipe via a /proc/*/fd/ pathname. |
| The inotify functionality in Linux kernel 2.6 before 2.6.28-rc5 might allow local users to gain privileges via unknown vectors related to race conditions in inotify watch removal and umount. |
| Vulnerable cross-model authorization in juju. If a charm's cross-model permissions are revoked or expire, a malicious user who is able to update database records can mint an invalid macaroon that is incorrectly validated by the juju controller, enabling a charm to maintain otherwise revoked or expired permissions. This allows a charm to continue relating to another charm in a cross-model relation, and use their workload without their permission. No fix is available as of the time of writing. |
| iccDEV provides a set of libraries and tools for working with ICC color management profiles. Prior to 2.3.1.5, there is a heap-use-after-free in CIccCmm::AddXform() causing invalid vptr dereference and crash. This vulnerability is fixed in 2.3.1.5. |
| In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: fix inverted genmask check in nft_map_catchall_activate()
nft_map_catchall_activate() has an inverted element activity check
compared to its non-catchall counterpart nft_mapelem_activate() and
compared to what is logically required.
nft_map_catchall_activate() is called from the abort path to re-activate
catchall map elements that were deactivated during a failed transaction.
It should skip elements that are already active (they don't need
re-activation) and process elements that are inactive (they need to be
restored). Instead, the current code does the opposite: it skips inactive
elements and processes active ones.
Compare the non-catchall activate callback, which is correct:
nft_mapelem_activate():
if (nft_set_elem_active(ext, iter->genmask))
return 0; /* skip active, process inactive */
With the buggy catchall version:
nft_map_catchall_activate():
if (!nft_set_elem_active(ext, genmask))
continue; /* skip inactive, process active */
The consequence is that when a DELSET operation is aborted,
nft_setelem_data_activate() is never called for the catchall element.
For NFT_GOTO verdict elements, this means nft_data_hold() is never
called to restore the chain->use reference count. Each abort cycle
permanently decrements chain->use. Once chain->use reaches zero,
DELCHAIN succeeds and frees the chain while catchall verdict elements
still reference it, resulting in a use-after-free.
This is exploitable for local privilege escalation from an unprivileged
user via user namespaces + nftables on distributions that enable
CONFIG_USER_NS and CONFIG_NF_TABLES.
Fix by removing the negation so the check matches nft_mapelem_activate():
skip active elements, process inactive ones. |
| In the Linux kernel, the following vulnerability has been resolved:
NFSD: free copynotify stateid in nfs4_free_ol_stateid()
Typically copynotify stateid is freed either when parent's stateid
is being close/freed or in nfsd4_laundromat if the stateid hasn't
been used in a lease period.
However, in case when the server got an OPEN (which created
a parent stateid), followed by a COPY_NOTIFY using that stateid,
followed by a client reboot. New client instance while doing
CREATE_SESSION would force expire previous state of this client.
It leads to the open state being freed thru release_openowner->
nfs4_free_ol_stateid() and it finds that it still has copynotify
stateid associated with it. We currently print a warning and is
triggerred
WARNING: CPU: 1 PID: 8858 at fs/nfsd/nfs4state.c:1550 nfs4_free_ol_stateid+0xb0/0x100 [nfsd]
This patch, instead, frees the associated copynotify stateid here.
If the parent stateid is freed (without freeing the copynotify
stateids associated with it), it leads to the list corruption
when laundromat ends up freeing the copynotify state later.

| Amazon Cloud Cam is a home security camera that was deprecated on December 2, 2022, is end of life, and is no longer actively supported.
When a user powers on the Amazon Cloud Cam, the device attempts to connect to a remote service infrastructure that has been deprecated due to end-of-life status. The device defaults to a pairing status in which an arbitrary user can bypass SSL pinning to associate the device to an arbitrary network, allowing for network traffic interception and modification.
We recommend customers discontinue usage of any remaining Amazon Cloud Cams. |
| A flaw was found in the QEMU Virtio PCI Bindings (hw/virtio/virtio-pci.c). An improper release and use of the irqfd for vector 0 during the boot process leads to a guest triggerable crash via vhost_net_stop(). This flaw allows a malicious guest to crash the QEMU process on the host. |
| Reference to Expired Domain Vulnerability in OpenText™ ArcSight Enterprise Security Manager. |
| JWK Set (JSON Web Key Set) is a JWK and JWK Set Go implementation. Prior to 0.6.0, the project's provided HTTP client's local JWK Set cache should do a full replacement when the goroutine refreshes the remote JWK Set. The current behavior is to overwrite or append. This is a security issue for use cases that utilize the provided auto-caching HTTP client and where key removal from a JWK Set is equivalent to revocation. The affected auto-caching HTTP client was added in version v0.5.0 and fixed in v0.6.0. The only workaround would be to remove the provided auto-caching HTTP client and replace it with a custom implementation. This involves setting the HTTPClientStorageOptions.RefreshInterval to zero (or not specifying the value). |
