medium Tenable Cloud Security Plugin ID 464212

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: regulator: core: fix NULL dereference
 on unbind due to stale coupling data Failing to reset coupling_desc.n_coupled after freeing coupled_rdevs
 can lead to NULL pointer dereference when regulators are accessed post-unbind. This can happen during
 runtime PM or other regulator operations that rely on coupling metadata. For example, on ridesx4,
 unbinding the 'reg-dummy' platform device triggers a panic in regulator_lock_recursive() due to stale
 coupling state. Ensure n_coupled is set to 0 to prevent access to invalid pointers. (CVE-2025-38668)

Solution

Update the linux library and its related packages to version 6.1.148-1 or later.
