DescriptionCVE.org
Use After Free vulnerability in Arm Ltd Bifrost GPU Kernel Driver, Arm Ltd Valhall GPU Kernel Driver, Arm Ltd Arm 5th Gen GPU Architecture Kernel Driver allows a local non-privileged user process to perform valid GPU memory processing operations to gain access to already freed memory.This issue affects Bifrost GPU Kernel Driver: from r44p0 through r49p3, from r50p0 through r51p0; Valhall GPU Kernel Driver: from r44p0 through r49p3, from r50p0 through r54p0; Arm 5th Gen GPU Architecture Kernel Driver: from r44p0 through r49p3, from r50p0 through r54p0.
Executive ViewAI
A use-after-free vulnerability in Arm GPU kernel drivers affects devices using Bifrost, Valhall, and 5th Gen GPU architectures, allowing local attackers to access freed memory and potentially escalate privileges or compromise system integrity. Organizations with Android devices, embedded systems, or edge computing platforms using affected Arm GPUs require immediate assessment and mitigation planning, as no patch is currently available.
Restrict local user account creation and SSH access on affected systems; enforce mandatory access controls (SELinux/AppArmor) with strict GPU resource isolation; disable GPU compute features if not critical to operations; implement kernel-level auditing for GPU memory operations; isolate affected devices from sensitive networks; deploy endpoint detection and response (EDR) tools to monitor for privilege escalation attempts; require multi-factor authentication for local system access.
