CVE-2026-89886Hinoki check available

Kernel memory consumption via notifier cleanup omission

Published Sep 16, 2026 · Updated Sep 16, 2026

Resource leak in the Intel IPU6 media driver in Linux 6.10 allows attackers to consume kernel memory through notifier parse failures. The isys_notifier_init() error path returns after a partial endpoint parse without calling v4l2_async_nf_cleanup(), leaving each added v4l2_async_connection on the notifier waiting list. The public record does not identify how attackers can force repeated parse failures or whether the leak reaches a hang, crash, or reboot.
