CVE-2023-53011

System crash via missing safety feature configuration

Published Mar 27, 2025 · Updated May 11, 2026

NULL pointer dereference in the Linux kernel stmmac driver allows local users to crash affected hosts when opening an interface. When DWMAC5 hardware advertises the automotive safety package, __stmmac_open calls dwmac5_safety_feat_config with a missing safety_feat_cfg for platforms that never defined one. Low-privileged local access, the ability to bring the interface up, and affected DWMAC5 hardware are required; the resulting kernel fault crashes the host.
