Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A memory leak occurs in the tegra channel try format() function. The issue arises because two error paths return immediately after the v4l2 subdev call() function fails, failing to call v4l2 subdev state free() to release the sd state object previously allocated by v4l2 subdev state alloc().

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
