  "summary": "media: tegra-video: Fix memory leak in __tegra_channel_try_format()",
  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: tegra-video: Fix memory leak in __tegra_channel_try_format()\n\nThe state object allocated by __v4l2_subdev_state_alloc() must be freed\nwith __v4l2_subdev_state_free() when it is no longer needed.\n\nIn __tegra_channel_try_format(), two error paths return directly after\nv4l2_subdev_call() fails, without freeing the allocated 'sd_state'\nobject. This violates the requirement and causes a memory leak.\n\nFix this by introducing a cleanup label and using goto statements in the\nerror paths to ensure that __v4l2_subdev_state_free() is always called\nbefore the function returns.",
