Description
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: ptp_s390.c, ptp_vclock.c and ptp_mock.c.
Instead use a dummy callback if no better was specified by the driver.
Affected configurations
• linux linux kernel (>= 3.0 < 6.1.129)
• linux linux kernel (>= 6.2 < 6.6.78)
• linux linux kernel (>= 6.7 < 6.12.14)
• linux linux kernel (>= 6.13 < 6.13.3)
