Description
A flaw was found in the Linux kernel's amdgpu graphics driver, specifically within the sdma4.4.2 component. This vulnerability could allow a local attacker to trigger a system crash by exploiting certain unhandled error conditions. The issue stems from the use of a BUG_ON() macro, which forces a kernel panic and results in a Denial of Service (DoS). The resolution replaces this with a WARN_ON() macro, preventing the system from crashing while still logging the error.
Statement
This issue affects systems using the AMDGPU driver with SDMA 4.4.2. Certain error paths in the SDMA engine used BUG_ON(), which forces an immediate kernel panic. A local user able to exercise those GPU paths could trigger a denial of service. Systems without AMD GPUs are not affected.
