Name of the Vulnerable Software and Affected Versions:
Linux kernel (affected versions not specified)
Description:
The Linux kernel contains a use-after-free issue within the
composite dev cleanup() function. This occurs because a pointer, cdev->os desc req, may not be set to NULL after a kmalloc failure in configfs composite bind(). Subsequently, composite dev cleanup() attempts to use this potentially freed pointer, leading to the use-after-free condition. The issue is located in the configfs composite bind() and composite dev cleanup() functions.Recommendations:
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
