Linux CVE-2026-53380

Local privilege escalation and kernel memory disclosure in the Linux kernel's Renesas RZ/V2H IVC media driver (rzv2h-ivc) stems from a race condition where rzv2h_ivc_transfer_buffer() calls list_del() on the shared buffer queue from a workqueue context without holding the protecting spinlock. On affected embedded systems using the RZ/V2H SoC, a local low-privileged user can concurrently modify the buffer list to corrupt kernel memory, potentially leaking data or achieving code execution. EPSS is low (0.14%, 4th percentile) and there is no public exploit identified at time of analysis; the flaw is fixed upstream in the stable kernel tree.
