CVE-2026-53038

CVE-2026-53038 affects the Linux kernel IMA subsystem. When handling unsupported TPM hash algorithms, ima_fs can access hash_algo_name[] with an invalid crypto_id (set to HASH_ALGO__LAST), causing a read-out-of-bounds in create_securityfs_measurement_lists. The issue is associated with TPM_ALG_SH...
