Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A possible memory leak in the
ptp clock register() function has been resolved. The memory leak occurs when posix clock register() returns an error, causing the name allocated in dev set name() to be leaked. To fix this issue, the put device() function should be used to give up the device reference, allowing the name to be freed in kobject cleanup() and other memory to be freed in ptp clock release(). The leak was identified through a fault injection test, which revealed an unreferenced object.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
