Description SMASH SMASH 2024-02-26 09:09:25 UTC 
In the Linux kernel, the following vulnerability has been resolved:

drm/sched: Fix bounds limiting when given a malformed entity

If we're given a malformed entity in drm_sched_entity_init()--shouldn't
happen, but we verify--with out-of-bounds priority value, we set it to an
allowed value. Fix the expression which sets this limit.
