Google: sys-kernel/lakitu-kernel-6_1: security update to 18026.0.0

medium Tenable Cloud Security Plugin ID 451417

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: nf_tables: don't skip
 expired elements during walk There is an asymmetry between commit/abort and preparation phase if the
 following conditions are met: 1. set is a verdict map ("1.2.3.4 : jump foo") 2. timeouts are enabled In
 this case, following sequence is problematic: 1. element E in set S refers to chain C 2. userspace
 requests removal of set S 3. kernel does a set walk to decrement chain->use count for all elements from
 preparation phase 4. kernel does another set walk to remove elements from the commit phase (or another
 walk to do a chain->use increment for all elements from abort phase) If E has already expired in 1), it
 will be ignored during list walk, so its use count won't have been changed. Then, when set is culled,
 ->destroy callback will zap the element via nf_tables_set_elem_destroy(), but this function is only safe
 for elements that have been deactivated earlier from the preparation phase: lack of earlier deactivate
 removes the element but leaks the chain use count, which results in a WARN splat when the chain gets
 removed later, plus a leak of the nft_chain structure. Update pipapo_get() not to skip expired elements,
 otherwise flush command reports bogus ENOENT errors. (CVE-2023-52924)

Solution

Update the sys-kernel/lakitu-kernel-6_1 library and its related packages to version 18026.0.0 or later.
