- Summary
- ptp: unregister virtual clocks when unregistering physical clock.
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
ptp: unregister virtual clocks when unregistering physical clock.
When unregistering a physical clock which has some virtual clocks, unregister the virtual clocks with it.
This fixes the following oops, which can be triggered by unloading a driver providing a PTP clock when it has enabled virtual clocks:
