# Memory leak vulnerability in Mali GPU Kernel Driver in Midgard GPU Kernel Driver all versions from r6p0 - r32p0,…

An Arm Mali GPU kernel driver flaw lets a non-privileged local user run valid GPU operations that expose sensitive kernel metadata. CISA lists it as actively exploited in the wild.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:Arm Mali Graphics Processing Unit (GPU) affected ? fixed ?
- vendor:arm 5th gen gpu architecture kernel driver affected >= r41p0, < r43p0 fixed r43p0
- vendor:arm bifrost gpu kernel driver affected >= r0p0, < r43p0 fixed r43p0
- vendor:arm midgard gpu kernel driver affected >= r6p0, <= r32p0 fixed ?
- vendor:arm valhall gpu kernel driver affected >= r19p0, < r43p0 fixed r43p0

## Fix

Apply the updated Mali GPU kernel driver from Arm per vendor instructions; the affected and fixed versions are not stated in the sources.
