Google: sys-kernel/lakitu-kernel-6_1: security update to 18244.236.64

high Tenable Self-Hosted Container Security Plugin ID 450745

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: net: do not delay dst_entries_add() in
dst_release() dst_entries_add() uses per-cpu data that might be freed at netns dismantle from
ip6_route_net_exit() calling dst_entries_destroy() Before ip6_route_net_exit() can be called, we release
all the dsts associated with this netns, via calls to dst_release(), which waits an rcu grace period
before calling dst_destroy() dst_entries_add() use in dst_destroy() is racy, because dst_entries_destroy()
could have been called already. Decrementing the number of dsts must happen sooner. Notes: 1) in
CONFIG_XFRM case, dst_destroy() can call dst_release_immediate(child), this might also cause UAF if the
child does not have DST_NOCOUNT set. IPSEC maintainers might take a look and see how to address this. 2)
There is also discussion about removing this count of dst, which might happen in future kernels.
(CVE-2024-50036)
