CVE-2023-3357

System crash via unchecked DMA allocation failure

Published Jun 28, 2023 · Updated Mar 10, 2025

NULL pointer dereference in the AMD Sensor Fusion Hub driver in Linux Kernel 6.1-rc8 allows local users to crash the system. In amd_sfh_hid_client_init(), the driver continues initialization without checking whether dma_alloc_coherent() returned NULL, then uses the failed allocation. Exploitation requires local low-privileged access, AMD SFH hardware, and a DMA allocation failure; the bounded consequence is a system crash.
