CVE-2026-72259

Service interruption via unreleased reserved memory

Published Aug 15, 2026 · Updated Aug 15, 2026

Resource leak in the Linux kernel's MT8192 ASoC driver allows local users to interrupt service through reserved-memory exhaustion. The MT8192 AFE probe path assigns reserved memory but omits a release action after successful initialization, leaking the assignment on probe failure or driver unbind. Repeated lifecycle events on an MT8192 system with assigned reserved memory are required, and accumulated leakage can exhaust memory and destabilize the system.
