high Tenable Self-Hosted Container Security Plugin ID 469311

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: ACPI: processor: validate MADT IOAPIC
 entry bounds The IOAPIC hotplug lookup parses both MADT and _MAT records directly. The MADT walk
 previously used a subtable's declared length to advance the cursor after only locating a generic header.
 The _MAT path likewise passed a generic header to the IOAPIC helper. Validate that a current record has a
 complete generic header, that its declared length is contained in the available record range, and that a
 typed IOAPIC record contains the full fixed IOAPIC body before reading its fields. Use the same relation
 for both MADT and _MAT provider paths. (CVE-2026-92522)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.700.7 or later.
