CVE-2026-64166 is a vulnerability of currently unknown severity. In the Linux kernel, the following vulnerability has been resolved: firmware: arm_ffa: Check for NULL FF-A ID table while driver registration The bus match callback assumes that every FF-A driver provides an id_table and dereferences it unconditionally. Enforce that contract at registration time so a buggy client driver cannot crash the bus during match.. EPSS estimates a 0.17% chance of exploitation in the next 30 days.
