CVE-2026-9040

Local data disclosure or disruption via memory race

Published Sep 8, 2026 · Updated Sep 8, 2026

Race condition in Arm Mali GPU kernel drivers allows local users to disclose sensitive information or interrupt service through GPU operations. Arm identifies improper synchronization during GPU memory processing but does not disclose the affected function, object, or conflicting operations. A local non-privileged process must reach the GPU interface; successful exploitation exposes sensitive data or interrupts service without reported code execution.
