CVE-2026-53380 Details
Description
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]
A vulnerability in the Linux kernel's handling of buffer lists in the Renesas Input Video Control (IVC) driver can lead to concurrent modification issues. The vulnerability arises because the buffer list is managed with a spinlock, but the removal of buffers from the list can occur without holding the lock. This flaw allows for the possibility of the list being altered simultaneously from different contexts, potentially leading to undefined behavior or data corruption.
The vulnerability has been addressed in the official Linux kernel stable releases. Users can upgrade to the latest stable version to apply the fix.
