CVE-2026-43162

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

media: tegra-video: Fix memory leak in _tegrachanneltryformat()

The state object allocated by __v4l2subdevstate_alloc() must be freed with _v4l2subdevstatefree() when it is no longer needed.

In __tegrachanneltryformat(), two error paths return directly after v4l2subdevcall() fails, without freeing the allocated 'sdstate' object. This violates the requirement and causes a memory leak.

Fix this by introducing a cleanup label and using goto statements in the error paths to ensure that _v4l2subdevstatefree() is always called before the function returns.
