Calling `PACKET_ADD_MEMBERSHIP` on an ops-locked device can trigger
the `NETDEV_UNREGISTER` notifier, which may require disabling promiscuous
and/or allmulti mode. Both of these operations require acquiring
the netdev instance lock.
Move the call to `packet_dev_mc` outside of the RCU critical section.
The `mclist` modifications (add, del, flush, unregister) are protected by
the RTNL, not the RCU. The RCU only protects the `sklist` and its
associated `sks`. The delayed operation on the `mclist` entry remains
within the RTNL. |
| authentik is an open-source Identity Provider. Prior to versions 2025.8.5 and 2025.10.2, in previous authentik versions, invitations were considered valid regardless if they are expired or not, thus relying on background tasks to clean up expired ones. In a normal scenario this can take up to 5 minutes because the cleanup of expired objects is scheduled to run every 5 minutes. However, with a large amount of tasks in the backlog, this might take longer. authentik versions 2025.8.5 and 2025.10.2 fix this issue. A workaround involves creating a policy that explicitly checks whether the invitation is still valid, and then bind it to the invitation stage on the invitation flow, and denying access if the invitation is not valid. |
| An arithmetic overflow flaw was found in Satellite when creating a new personal access token. This flaw allows an attacker who uses this arithmetic overflow to create personal access tokens that are valid indefinitely, resulting in damage to the system's integrity. |
| A denial of service vulnerability was found in Keycloak that could allow an administrative user with the right to change realm settings to disrupt the service. This action is done by modifying any of the security headers and inserting newlines, which causes the Keycloak server to write to a request that has already been terminated, leading to the failure of said request. |
| A denial of service vulnerability was found in tipc_crypto_key_revoke in net/tipc/crypto.c in the Linux kernel’s TIPC subsystem. This flaw allows guests with local user privileges to trigger a deadlock and potentially crash the system. |
| A denial of service vulnerability due to a deadlock was found in sctp_auto_asconf_init in net/sctp/socket.c in the Linux kernel’s SCTP subsystem. This flaw allows guests with local user privileges to trigger a deadlock and potentially crash the system. |
| A flaw was found in libnbd, due to a malicious Network Block Device (NBD), a protocol for accessing Block Devices such as hard disks over a Network. This issue may allow a malicious NBD server to cause a Denial of Service. |
| A flaw was found In 3Scale Admin Portal. If a user logs out from the personal tokens page and then presses the back button in the browser, the tokens page is rendered from the browser cache. |
| A flaw was found in the Keylime registrar that could allow a bypass of the challenge-response protocol during agent registration. This issue may allow an attacker to impersonate an agent and hide the true status of a monitored machine if the fake agent is added to the verifier list by a legitimate user, resulting in a breach of the integrity of the registrar database. |

usb: typec: tcpm: move tcpm_queue_vdm_unlocked to asynchronous work
A state check was previously added to tcpm_queue_vdm_unlocked to
prevent a deadlock where the DisplayPort Alt Mode driver would be
executing work and attempting to grab the tcpm_lock while the TCPM
was holding the lock and attempting to unregister the altmode, blocking
on the altmode driver's cancel_work_sync call.
Because the state check isn't protected, there is a small window
where the Alt Mode driver could determine that the TCPM is
in a ready state and attempt to grab the lock while the
TCPM grabs the lock and changes the TCPM state to one that
causes the deadlock. The callstack is provided below:

Change tcpm_queue_vdm_unlocked to queue for tcpm_queue_vdm_work,
which can perform the state check while holding the TCPM lock
while the Alt Mode lock is no longer held. This requires a new
struct to hold the vdm data, altmode_vdm_event. |
| A flaw was found in PCP. The default pmproxy configuration exposes the Redis server backend to the local network, allowing remote command execution with the privileges of the Redis user. This issue can only be exploited when pmproxy is running. By default, pmproxy is not running and needs to be started manually. The pmproxy service is usually started from the 'Metrics settings' page of the Cockpit web interface. This flaw affects PCP versions 4.3.4 and newer. |
| A flaw was found in the tracker-miners package. A weakness in the sandbox allows a maliciously-crafted file to execute code outside the sandbox if the tracker-extract process has first been compromised by a separate vulnerability. |
| An issue has been discovered in GitLab affecting all versions starting from 4.1 before 16.1.5, all versions starting from 16.2 before 16.2.5, all versions starting from 16.3 before 16.3.1 where it was possible to create a URL that would redirect to a different project. |
| In the Linux kernel, the following vulnerability has been resolved:
fs/dax: Fix "don't skip locked entries when scanning entries"
Commit 6be3e21d25ca ("fs/dax: don't skip locked entries when scanning
entries") introduced a new function, wait_entry_unlocked_exclusive(),
which waits for the current entry to become unlocked without advancing
the XArray iterator state.
Waiting for the entry to become unlocked requires dropping the XArray
lock. This requires calling xas_pause() prior to dropping the lock
which leaves the xas in a suitable state for the next iteration. However
this has the side-effect of advancing the xas state to the next index.
Normally this isn't an issue because xas_for_each() contains code to
detect this state and thus avoid advancing the index a second time on
the next loop iteration.
However both callers of and wait_entry_unlocked_exclusive() itself
subsequently use the xas state to reload the entry. As xas_pause()
updated the state to the next index this will cause the current entry
which is being waited on to be skipped. This caused the following
warning to fire intermittently when running xftest generic/068 on an XFS
filesystem with FS DAX enabled:

| In the Linux kernel, the following vulnerability has been resolved:
wifi: ath12k: Prevent sending WMI commands to firmware during firmware crash
Currently, we encounter the following kernel call trace when a firmware
crash occurs. This happens because the host sends WMI commands to the
firmware while it is in recovery, causing the commands to fail and
resulting in the kernel call trace.
Set the ATH12K_FLAG_CRASH_FLUSH and ATH12K_FLAG_RECOVERY flags when the
host driver receives the firmware crash notification from MHI. This
prevents sending WMI commands to the firmware during recovery.

wifi: ath12k: fix node corruption in ar->arvifs list
In current WLAN recovery code flow, ath12k_core_halt() only reinitializes
the "arvifs" list head. This will cause the list node immediately following
the list head to become an invalid list node. Because the prev of that node
still points to the list head "arvifs", but the next of the list head
"arvifs" no longer points to that list node.
When a WLAN recovery occurs during the execution of a vif removal, and it
happens before the spin_lock_bh(&ar->data_lock) in
ath12k_mac_vdev_delete(), list_del() will detect the previously mentioned
situation, thereby triggering a kernel panic.
The fix is to remove and reinitialize all vif list nodes from the list head
"arvifs" during WLAN halt. The reinitialization is to make the list nodes
valid, ensuring that the list_del() in ath12k_mac_vdev_delete() can execute
normally.

| In the Linux kernel, the following vulnerability has been resolved:
block: don't use submit_bio_noacct_nocheck in blk_zone_wplug_bio_work
Bios queued up in the zone write plug have already gone through all all
preparation in the submit_bio path, including the freeze protection.
Submitting them through submit_bio_noacct_nocheck duplicates the work
and can can cause deadlocks when freezing a queue with pending bio
write plugs.
Go straight to ->submit_bio or blk_mq_submit_bio to bypass the
superfluous extra freeze protection and checks. |

firmware: arm_ffa: Replace mutex with rwlock to avoid sleep in atomic context
The current use of a mutex to protect the notifier hashtable accesses
can lead to issues in the atomic context. It results in the below
kernel warnings:

To address this, replace the mutex with an rwlock to protect the notifier
hashtable accesses. This ensures that read-side locking does not sleep and
multiple readers can acquire the lock concurrently, avoiding unnecessary
contention and potential deadlocks. Writer access remains exclusive,
preserving correctness.
This change resolves warnings from lockdep about potential sleep in
atomic context. |
