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

Description A possible memory leak has been identified in the Linux kernel, specifically in the iio sysfs trig init() function. The dev set name() function allocates memory for the name, which needs to be freed when device add() fails. The put device() function is called to release the reference held in device initialize(), allowing it to be freed in kobject cleanup() when the refcount reaches 0. A fault injection test can trigger this issue, resulting in an unreferenced object.

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