CWE ID 667
Summary
CVE-2024-46829 is a vulnerability affecting the Linux kernel. In the rtmutex subsystem, if the rt_mutex::wait_lock is held when rt_mutex_handle_deadlock() is called, the system will enter an endless scheduling loop, resulting in a deadlock. This issue can trigger a 'scheduling in atomic' warning. To mitigate this vulnerability, the order of operations in rt_mutex_handle_deadlock() has been corrected to unlock rt_mutex::wait_lock before issuing the warning and dropping into the scheduling loop.
