- Details
-
In the Linux kernel, the following vulnerability has been resolved:
arm_mpam: Fix a NULL pointer dereference on unbinding after an error interrupt
If a user unbinds an MSC after mpam_disable() has been run in response to an error interrupt then a dereference of a NULL pointer occurs as mpam_disable() sets the drvdata to NULL. Add an early return to the driver remove callback to avoid this.
