high Tenable Cloud Security Plugin ID 470958

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: xsk: validate metadata when processing
requests The zero-copy path validates TX metadata while obtaining the descriptor context, then reads it
again later when preparing the hardware request. User space can change the metadata between those
operations and bypass the original validation. Validate the metadata in xsk_tx_metadata_request() and use
the resulting flags snapshot for every feature check. Read request fields once so all zero-copy drivers
process only values observed after successful validation. (CVE-2026-74707)

Solution

Update the sys-kernel/cchost-kernel-6_18 library and its related packages to version 19999.44.28 or later.
