Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A vulnerability in the Linux kernel has been resolved. The issue arises from the ioctl and sysfs handlers unconditionally calling the
->enable callback, which can lead to NULL dereferences if not all drivers implement this callback. Affected drivers include ptp s390.c, ptp vclock.c, and ptp mock.c. To address this, a dummy callback is used if no better callback was specified by the driver.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
