Description
A flaw was found in the AMD GPU driver within the Linux kernel. When handling overflow conditions in the Common Platform Error Record (CPER) ring buffer, the driver relies on parsed entry sizes from the buffer contents without verifying that the read pointer advances. Corrupt error record data can cause the recovery loop to repeat indefinitely while holding a ring lock. This issue can cause kernel worker threads to hang, resulting in a denial of service.
