Overview

CVE-2024-46829 is a medium-severity vulnerability. It was published on September 27, 2024 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

Technical description

In the Linux kernel, the following vulnerability has been resolved:

rtmutex: Drop rt_mutex::wait_lock before scheduling

rt_mutex_handle_deadlock() is called with rt_mutex::wait_lock held. In the

good case it returns with the lock held and in the deadlock case it emits a

warning and goes into an endless scheduling loop with the lock held, which

triggers the 'scheduling in atomic' warning.

Unlock rt_mutex::wait_lock in the dead lock case before issuing the warning

and dropping into the schedule for ever loop.

[ tglx: Moved unlock before the WARN(), removed the pointless comment,

massaged changelog, added Fixes tag ]

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
