Memory leak vulnerability in Mali GPU Kernel Driver in Midgard GPU Kernel Driver all versions from r6p0 - r32p0, Bifrost GPU Kernel Driver all versions from r0p0 - r42p0, Valhall GPU Kernel Driver all versions from r19p0 - r42p0, and Avalon GPU Kernel Driver all versions from r41p0 - r42p0 allows a non-privileged user to make valid GPU processing operations that expose sensitive kernel metadata.
What To Do Now
- 1
Find it
Search your asset inventory and external attack surface for Arm Mali Graphics Processing Unit (GPU). Include cloud images, appliances and anything a supplier runs for you.
Attack Surface Management - 2
- 3
Hunt for compromise
If an affected system was reachable before you patched, assume it may have been hit. Check logs, new accounts, web shells and outbound connections from the date of exposure.
Incident Response - 4
Prove it is fixed
Rescan or test the system after patching. Upgrades that fail silently and forgotten secondary instances are common.
