medium Tenable Self-Hosted Container Security Plugin ID 468655

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: Unregister cpufreq
notifier on init failure acpi_processor_driver_init() registers the cpufreq policy notifier before
registering the ACPI processor driver and setting up CPU hotplug state. If driver_register() or
cpuhp_setup_state() fails, the error path only unregisters the ACPI processor driver and the idle driver.
The cpufreq notifier remains registered even though initialization failed. Mirror the module exit path on
the init failure path and unregister the cpufreq notifier when it has been registered. (CVE-2026-90364)

Solution

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