High (8.8) in Arm Mali Graphics Processing Unit (GPU). In CISA KEV since 2023-07-07. EPSS 3.0% chance of exploitation in the next 30 days.
. The Arm Mali GPU kernel driver allows an unprivileged user to achieve access to freed memory, leading to information disclosure or root privilege escalation. This affects Bifrost r16p0 through r29p0 before r30p0, Valhall r19p0 through r29p0 before r30p0, and Midgard r28p0 through r30p0.
