medium Tenable Cloud Security Plugin ID 468910

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: netfilter: nft_counter: serialize
reset with spinlock Add a global static spinlock to serialize counter fetch+reset operations, preventing
concurrent dump-and-reset from underrunning values. The lock is taken before fetching the total so that
two parallel resets cannot both read the same counter values and then both subtract them. A global lock is
used for simplicity since resets are infrequent. If this becomes a bottleneck, it can be replaced with a
per-net lock later. (CVE-2026-45897)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.655.6 or later.
