Description SMASH SMASH 2024-06-04 07:49:10 UTC 
In the Linux kernel, the following vulnerability has been resolved:

drm/amdkfd: range check cp bad op exception interrupts

Due to a CP interrupt bug, bad packet garbage exception codes are raised.
Do a range check so that the debugger and runtime do not receive garbage
codes.
Update the user api to guard exception code type checking as well.
