high Tenable Cloud Security Plugin ID 475712

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: acomp - allocate async request
 context when cloning ACOMP_REQUEST_ON_STACK() reserves only enough storage for the synchronous fallback.
 When an async implementation is selected, callers clone that stack request before retrying, but
 acomp_request_clone() currently copies only the stack-sized object. The clone therefore has no storage for
 the async provider request context, and providers such as QAT write past the allocation through
 acomp_request_ctx(). KASAN does report a slab OOB write. Allocate a zeroed clone large enough for the
 runtime acomp request size, copy only the bytes present in the source object, and preserve the existing
 fallback-on-allocation-failure behavior. Use the runtime reqsize because an implementation may adjust it
 during tfm initialization. (CVE-2026-90069)

Solution

Update the sys-kernel/cchost-kernel-6_18 library and its related packages to version 20198.0.0 or later.
