  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nfirmware: arm_ffa: Check for NULL FF-A ID table while driver registration\n\nThe bus match callback assumes that every FF-A driver provides an\nid_table and dereferences it unconditionally. Enforce that contract at\nregistration time so a buggy client driver cannot crash the bus during\nmatch.",
