Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A race condition exists within the hidp session thread function, potentially leading to a use-after-free issue. Specifically, the timer may remain active while hidp del timer is invoked within the same thread. Subsequently, the session is freed after hidp session put, resulting in a kernel panic when hidp idle timeout is executed. The call trace includes functions such as hidp session probe, call timer fn, and run timers.part.0.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
