Description
A flaw was found in the Linux kernel's AMD GPU driver (amdkfd). When enabling a debug trap fails during data transfer to user space, the kernel fails to clean up previously allocated resources and state, leaving an inconsistent trap state and an unreleased process reference count. A local attacker could exploit this flaw to cause a Denial of Service (DoS) by disrupting subsequent debugging operations or degrading system stability.
