Google: sys-kernel/cchost-kernel-6_12, sys-kernel/csql-kernel-6_6: security update to 19216.220.185

medium Tenable Cloud Security Plugin ID 469474

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: crypto: af_alg - limit RX SG
extraction by receive buffer budget Make af_alg_get_rsgl() limit each RX scatterlist extraction to the
remaining receive buffer budget. af_alg_get_rsgl() currently uses af_alg_readable() only as a gate before
extracting data into the RX scatterlist. Limit each extraction to the remaining af_alg_rcvbuf(sk) budget
so that receive-side accounting matches the amount of data attached to the request. If skcipher cannot
obtain enough RX space for at least one chunk while more data remains to be processed, reject the recvmsg
call instead of rounding the request length down to zero. (CVE-2026-31677)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.220.185 or later.
