Details

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

net/mlx5: Add a timeout to acquire the command queue semaphore

Prevent forced completion handling on an entry that has not yet been assigned an index, causing an out of bounds access on idx = -22. Instead of waiting indefinitely for the sem, blocking flow now waits for index to be allocated or a sem acquisition timeout before beginning the timer for FW completion.

Kernel log example: mlx5core 0000:06:00.0: waitfunchandleexectimeout:1128:(pid 185911): cmd[-22]: CREATEUCTX(0xa04) No done completion
