Name of the Vulnerable Software and Affected Versions Linux kernel versions 6.7.0

Description A potential deadlock can occur when enabling ASPM during the probe of Qualcomm PCIe controllers, as reported by lockdep. This issue is caused by a possible recursive locking scenario where a task tries to acquire a lock that it already holds, leading to a deadlock. The deadlock can be easily reproduced on machines like the Lenovo ThinkPad X13s by adding a delay to increase the race window during asynchronous probe, allowing another thread to take a write lock.

Recommendations For Linux kernel version 6.7.0, update to a newer version that includes the fix for the deadlock issue, which introduces a new pci set power state locked() function and associated helper functions to avoid taking the read lock twice.
