# Arm Mali GPU Kernel Driver allows a non-privileged user to achieve write access to read-only memory pages

Arm Mali GPU kernel driver has an unspecified flaw that lets a non-privileged local user write to read-only memory pages. This is a kernel-level memory write, so an attacker who already runs code on the device can escalate privileges.

_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 bifrost gpu kernel driver affected >= r0p0, < r36p0 fixed r36p0
- vendor:arm midgard gpu kernel driver affected >= r26p0, < r32p0 fixed r32p0
- vendor:arm valhall gpu kernel driver affected >= r19p0, < r36p0 fixed r36p0

## Fix

Apply the vendor updates per Arm's advisory for the Mali GPU kernel driver; the affected and fixed driver versions are unknown from the sources.
CISA's KEV entry requires applying updates per vendor instructions.

## From the sources

Arm Mali GPU Kernel Driver contains an unspecified vulnerability that allows a non-privileged user to achieve write access to read-only memory pages.

CISA required action: Apply updates per vendor instructions.
