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

Description The Linux kernel contains a memory leak in the ptp qoriq probe() function within the ptp qoriq module. Smatch, a static analysis tool, identified that memory allocated using ioremap() for the base variable was not being released under specific error conditions, specifically when ptp qoriq init() returns on the first -ENODEV error path. The issue is addressed by revising the parameter passed to the function.

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