CVE-2026-9040
UnknownSummary
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.
Risk Assessment
The risk includes local privilege escalation or data disclosure, which may lead to system confidentiality breaches and service disruption.
Recommendation
It is recommended to update Arm GPU kernel drivers to versions containing a fix and to restrict local user access to GPU operations if possible.
