Description
The Arm Mali GPU kernel driver allows privilege escalation or a denial of service (memory corruption) because an unprivileged user can achieve read/write access to read-only pages. This affects Bifrost r0p0 through r29p0 before r30p0, Valhall r19p0 through r29p0 before r30p0, and Midgard r8p0 through r30p0 before r31p0.
Affected configurations
• arm bifrost gpu kernel driver (>= r0p0 < r29p0)
• arm midgard gpu kernel driver (>= r8p0 < r31p0)
• arm valhall gpu kernel driver (>= r19p0 < r29p0)
