medium Tenable Cloud Security Plugin ID 472114

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: driver: Check ACPI_COMPANION()
against NULL during probe Since every platform driver can be forced to match a device that doesn't match
its list of device IDs because of device_match_driver_override(), platform drivers that rely on the
existence of a device's ACPI companion object should verify its presence. Accordingly, add requisite
ACPI_COMPANION() or ACPI_HANDLE() checks against NULL to 13 platform drivers handling core ACPI devices.
Also change the value returned by the ACPI thermal zone driver when the device's ACPI companion is not
present to -ENODEV for consistency with the other drivers. (CVE-2026-64227)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19506.299.116 or later.
