Google: sys-kernel/cchost-kernel-6_12, sys-kernel/csql-kernel-6_12, sys-kernel/lakitu-kernel-6_12, sys-kernel/lakitu-nc-kernel-6_12: security update to 19506.448.8

critical Tenable Self-Hosted Container Security Plugin ID 469274

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_lookup: fix catchall
element handling with inverted lookups nft_lookup_eval() decides whether a lookup matched (`found`) from
the direct set lookup and priv->invert before falling back to the catchall element used by interval sets
(e.g. nft_set_rbtree) for the open-ended default range. Since `found` is never recomputed after `ext` is
replaced by the catchall lookup, inverted lookups (NFT_LOOKUP_F_INV, "!= @set") can wrongly match or
wrongly skip the catchall element, producing the wrong verdict. Fold the catchall lookup into `ext` before
computing `found`, matching the order already used by nft_objref_map_eval(). (CVE-2026-72320)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19506.448.8 or later.
