CVE-2026-53380

Kernel memory corruption via unlocked list deletion

Published Jul 19, 2026 · Updated Jul 19, 2026

Race condition in the RZ/V2H IVC media driver in Linux Kernel 6.19 allows local users to corrupt kernel memory through concurrent access. The rzv2h_ivc_transfer_buffer() workqueue calls list_del() on rzv2h_ivc::buffers.queue without holding buffers.lock, allowing concurrent list mutation. Local low-privileged access is required; published sources do not identify a trigger interface or demonstrated exploit consequence.
