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

Description A memory leak exists in the nvmem register() function within the Linux kernel's nvmem core. The dev set name function allocates memory for nvmem->dev.kobj.name, but this memory is not freed if nvmem validate keepouts() fails before the device is registered. Moving nvmem validate keepouts() after device register() allows the device core to handle cleaning up the name in error cases, resolving the memory leak.

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