Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: ipv6: addrconf: bail out of
dad_failure when state is no longer POSTDAD addrconf_dad_failure() transitions ifp->state from DAD to
POSTDAD via addrconf_dad_end(), which drops ifp->lock on return. The lock is re-acquired after
net_info_ratelimited(). A concurrent ipv6_del_addr() can take the lock in that window, set ifp->state to
DEAD and run list_del_rcu(&ifp->if_list). addrconf_dad_failure() then overwrites DEAD with ERRDAD at
errdad: and schedules a new dad_work. The work calls ipv6_del_addr() again, hitting the already-poisoned
list entry: general protection fault: 0000 [#1] SMP NOPTI CPU: 4 PID: 217 Comm: kworker/4:1 Workqueue:
ipv6_addrconf addrconf_dad_work RIP: 0010:ipv6_del_addr+0xe9/0x280 RAX: dead000000000122 Call Trace:
addrconf_dad_stop+0x113/0x140 addrconf_dad_work+0x28c/0x430 process_one_work+0x1eb/0x3b0
worker_thread+0x4d/0x400 kthread+0x104/0x140 ret_from_fork+0x35/0x40 Fold the addrconf_dad_end() logic
into addrconf_dad_failure() under a single ifp->lock critical section. The STABLE_PRIVACY branch
temporarily drops ifp->lock around address regeneration, so at lock_errdad: verify the state is still
POSTDAD before transitioning to ERRDAD; bail out otherwise to avoid overwriting a state set by another
path while the lock was released. (CVE-2026-74398)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.731.2 or later.
