CVE-2024-58008

Kernel crash via vmalloc-backed scatterlist buffer

Published Feb 27, 2025 · Updated Aug 5, 2026

Denial of service in Linux 6.10.7 through 6.11 allows local users to crash the kernel through DCP trusted-key operations. The DCP backend passes the vmalloc-backed plain_key_blob stack buffer to sg_init_one(), creating an invalid scatterlist mapping. The crash requires CONFIG_VMAP_STACK and use of the DCP trusted-key backend; the reported consequence is limited to service interruption.
