Memory disclosure via malformed SR-IOV command
Published May 15, 2026 · Updated May 15, 2026
Out-of-bounds read in the AMD Secure Processor TEE SOC Driver on affected GPUs allows local administrators to expose driver memory. The driver insufficiently sanitizes parameters in a malformed DRV_SOC_CMD_ID_LOAD_GFX_IP_FW SR-IOV command before reading beyond its intended bounds. Reaching the flaw requires high local privileges and SR-IOV command access; successful exploitation discloses driver memory or triggers an exception.
