A race condition 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 improper GPU memory processing operations to cause a denial of service or disclose sensitive information.
This issue affects Bifrost GPU Kernel Driver: from r12p0 through r49p5, from r50p0 through r51p0, from r54p1 through r54p2; Valhall GPU Kernel Driver: from r19p0 through r49p5, from r50p0 through r54p3, r55p0; Arm 5th Gen GPU Architecture Kernel Driver: from r41p0 through r49p5, from r50p0 through r54p3, r55p0.
AnalysisAI
Race condition exploitation in Arm's Bifrost, Valhall, and 5th Gen GPU Architecture Kernel Drivers allows any local non-privileged process to perform improper GPU memory operations, yielding kernel-level sensitive information disclosure or denial of service. All three driver families are affected across broad version ranges spanning multiple major release trains - Bifrost from r12p0, Valhall from r19p0, and 5th Gen from r41p0 - covering a large installed base of Mali GPU-equipped devices. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the ability to execute local code on a device running one of the affected Arm GPU kernel drivers - no network access is needed. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 7.7 score (AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H) indicates local exploitation with no privileges required and no user interaction - any process that can open the GPU device node is a potential attacker. … 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 | Patch available per vendor advisory - consult the Arm security bulletin at https://support.arm.com/documentation/111552/1-0/?lang=en for exact fixed driver versions for each GPU family; exact patched release identifiers are not stated in the available data and should not be inferred from the vulnerable version ranges alone. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all Mali GPU-equipped devices in your organization (including Android phones, tablets, and ARM-based servers) and document which handle encryption, authentication, or payment data. …
