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: fix fib6 walker UAF on seq stop
ipv6_route_iter_active() treats a walker in FWS_U at the table root as already unlinked. fib6_del_route()
can move a still-linked walker into that same state when the current leaf is the last route at the root,
so ipv6_route_native_seq_stop() skips fib6_walker_unlink(). The seq private object can then be freed while
it remains on net->ipv6.fib6_walkers. A later route deletion walks the dangling list and uses the freed
walker. Use the list head as membership state and reinitialize it when unlinking. Keep the existing
w->node check so a never-started iterator with a zeroed private object is not treated as linked. The same
stop helper is used by /proc/net/ipv6_route and by the BPF ipv6_route iterator. The BPF show path only
widens the race. (CVE-2026-97940)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19999.44.106 or later.
