Vulnerability Details CVE-2026-53380
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]
