Summary
ptp: Ensure info->enable callback is always set
Details

In the Linux kernel, the following vulnerability has been resolved:

ptp: Ensure info->enable callback is always set

The ioctl and sysfs handlers unconditionally call the ->enable callback. Not all drivers implement that callback, leading to NULL dereferences. Example of affected drivers: ptps390.c, ptpvclock.c and ptp_mock.c.

Instead use a dummy callback if no better was specified by the driver.
