Vulnerability from fkie_nvd - Published: 2026-05-06 12:16 - Updated: 2026-05-13 21:19

Severity ?

5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

Summary

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.

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."
