CVE-2026-43162
In the Linux kernel, the following vulnerability has been resolved: media: tegra-video: Fix memory leak in __tegra_channel_try_format() The state object allocated by __v4l2_subdev_state_alloc() must be freed with __v4l2_subdev_state_free() when it is no longer needed. In __tegra_channel_try_format(), two error paths return directly after v4l2_subdev_call() fails, without freeing the allocated 'sd_state' 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 __v4l2_subdev_state_free() is always called before the function returns.
