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 access already freed memory.
This issue affects Bifrost GPU Kernel Driver: from r41p0 through r49p5, from r50p0 through r51p0, from r54p1 through r54p2; Valhall GPU Kernel Driver: from r41p0 through r49p5, from r50p0 through r54p3, r55p0; Arm 5th Gen GPU Architecture Kernel Driver: from r41p0 through r49p5, from r50p0 through r54p3, r55p0.
AnalysisAI
Use-after-free in Arm's Bifrost, Valhall, and 5th Gen GPU Architecture Kernel Drivers allows a local non-privileged process to access already-freed GPU memory through otherwise-valid GPU memory processing operations. The flaw spans a wide range of driver releases across all three GPU families - covering most modern Arm Mali GPU generations deployed in Android SoCs from r41p0 onward. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires local code execution as a non-privileged user on a device whose kernel is running one of the three affected Arm Mali GPU drivers (Bifrost r41p0-r54p2, Valhall r41p0-r55p0, or 5th Gen r41p0-r55p0). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS 5.1 (Medium) with AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N reflects a locally exploitable flaw requiring no authentication, but with limited impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade to a driver release that addresses this vulnerability: for Bifrost GPU Kernel Driver, upgrade beyond r54p2; for Valhall GPU Kernel Driver, upgrade beyond r55p0; for Arm 5th Gen GPU Architecture Kernel Driver, upgrade beyond r55p0. … Detailed patch versions, workarounds, and compensating controls in full report. |
