CVE-2026-53380

Summary

In the Linux kernel, the following vulnerability has been resolved:

media: rzv2h-ivc: Fix concurrent buffer list access

The list of buffers (rzv2h_ivc::buffers.queue) is protected by a spinlock (rzv2h_ivc::buffers.lock). However, in rzv2h_ivc_transfer_buffer(), which runs in a separate workqueue, the list_del() call is executed without holding the spinlock, which makes it possible for the list to be concurrently modified

Fix that by removing a buffer from the list in the lock protected section.

[assign ivc->buffers.curr in critical section as reported by Barnabas]
