Description
. 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.
Affected configurations
• arm bifrost gpu kernel driver (>= r16p0 < r30p0)
• arm midgard gpu kernel driver (>= r28p0 < r31p0)
• arm valhall gpu kernel driver (>= r19p0 < r30p0)
