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

Description The Linux kernel contains a memory leak issue within the add mtd device() function. Specifically, a kernel memory leak (kmemleak) occurs when device registration fails. This is due to a missing call to put device() to release the reference when the registration process fails. The leak involves an unreferenced object of size 8 bytes, observed in the context of the 'insmod' process. The backtrace indicates the issue originates from the add mtd device() function and related kernel functions involved in device registration.

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