Local kernel compromise via failed Tegra initialization
Published Mar 6, 2025 · Updated Aug 5, 2026
Memory corruption in Tegra crypto in Linux 6.10 through 6.12.12 and 6.13 through 6.13.1 allows local users to compromise the kernel via AF_ALG. After tegra_cmac_init() or tegra_sha_init() fails under memory pressure, the digest path still queues the request with freed, stale, or uninitialized buffer pointers. An unprivileged local user can induce allocation failure and submit hash data, enabling kernel-memory disclosure, controlled writes, or a kernel panic on systems using the Tegra Security Engine.
