EPSS Score1.2%

EPSS (Exploit Prediction Scoring System) estimates a 1.2% chance this CVE is exploited in the wild within the next 30 days — higher than 68% of all CVEs. It complements CVSS: a high EPSS on a mid-severity CVE can still be urgent.

Arm Mali GPU Kernel Driver contains an information disclosure vulnerability that allows a non-privileged user to make valid GPU processing operations that expose sensitive kernel metadata.
