Description

An issue was discovered in the Arm Mali GPU Kernel Driver. A non-privileged user can make improper GPU processing operations to gain access to already freed memory. This affects Valhall r29p0 through r42p0 before r43p0, and Arm's GPU Architecture Gen5 r41p0 through r42p0 before r43p0.

Affected

Our own answer: ranges merged, affected separated from platform-only, with confidence and review flags.

r41p0 ≤ v < r43p0
Affected range stops below r43p0, so it looks safe — our inference, not a vendor statement
r29p0 ≤ v < r43p0
Affected range stops below r43p0, so it looks safe — our inference, not a vendor statement
