Positive Technologies (AI Summary)

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

Description The Linux kernel contains a flaw within the drm/amdkfd subsystem that could lead to use-after-free (UAF) issues with kgd mem pointers. Specifically, pointers returned by the kfd process device translate handle function are only valid while a mutex lock is held. Once the mutex is unlocked, another thread may free the associated memory, creating a UAF condition.

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