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

Description The Linux kernel contains a memory leak in the test firmware init() function. Specifically, when misc register() fails during initialization, the memory pointed to by test fw config->name is not released, leading to a memory leak. The leaked memory is allocated using kstrndup() after a call to kmalloc node track caller(). The backtrace indicates the issue originates within the test firmware module.

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