AI-suggested

Description
A use-after-free vulnerability in the Linux kernel's drm/imagination driver was fixed by ensuring that the fragment job holds a reference to the paired geometry job, preventing premature freeing. This flaw was detected by KASAN and could lead to memory corruption during GPU job scheduling.
