CVE-2024-26876

Kernel crash via premature ADV7511 IRQ registration

Published Apr 17, 2024 · Updated May 11, 2026

Use of uninitialized data in the ADV7511 bridge driver in affected Linux kernels allows local users to crash the kernel during probe. adv7511_probe registers the IRQ before adv7511_cec_init initializes CEC state, so a pending interrupt reaches cec_received_msg_ts with unreadable data. Exploitation requires an ADV7511 device and a pending IRQ during driver probe; the documented result is an availability-only kernel oops.
