medium Tenable Self-Hosted Container Security Plugin ID 450933

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: x86/sev: Evict cache lines during SNP
memory validation An SNP cache coherency vulnerability requires a cache line eviction mitigation when
validating memory after a page state change to private. The specific mitigation is to touch the first and
last byte of each 4K page that is being validated. There is no need to perform the mitigation when
performing a page state change to shared and rescinding validation. CPUID bit Fn8000001F_EBX[31] defines
the COHERENCY_SFW_NO CPUID bit that, when set, indicates that the software mitigation for this
vulnerability is not needed. Implement the mitigation and invoke it when validating memory (making it
private) and the COHERENCY_SFW_NO bit is not set, indicating the SNP guest is vulnerable. (CVE-2025-38560)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18244.448.50 or later.
