Echo: linux: security update to 6.12.94-1

high Tenable Self-Hosted Container Security Plugin ID 458724

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: hwmon: (pmbus/core) Protect regulator
 operations with mutex The regulator operations pmbus_regulator_get_voltage(),
 pmbus_regulator_set_voltage(), and pmbus_regulator_list_voltage() access PMBus registers and shared data
 but were not protected by the update_lock mutex. This could lead to race conditions. However, adding mutex
 protection directly to these functions causes a deadlock because pmbus_regulator_notify() (which calls
 regulator_notifier_call_chain()) is often called with the mutex already held (e.g., from
 pmbus_fault_handler()). If a regulator callback then calls one of the now-protected voltage functions, it
 will attempt to acquire the same mutex. Rework pmbus_regulator_notify() to utilize a worker function to
 send notifications outside of the mutex protection. Events are stored as atomics in a per-page bitmask and
 processed by the worker. Initialize the worker and its associated data during regulator registration, and
 ensure it is cancelled on device removal using devm_add_action_or_reset(). While at it, remove the
 unnecessary include of linux/of.h. (CVE-2026-31486)

Solution

Update the linux library and its related packages to version 6.12.94-1 or later.
