CVE-2026-72259: ASoC: mediatek: mt8192: Release reserved memory on cleanup

Published Aug 15, 2026

Updated

In the Linux kernel, the following vulnerability has been resolved:

ASoC: mediatek: mt8192: Release reserved memory on cleanup

The MT8192 AFE probe calls ofreservedmemdeviceinit() and falls back to preallocated buffers when no reserved memory region is available. When the reserved memory assignment succeeds, however, the driver never releases it.

Register a devm cleanup action after a successful reserved-memory assignment so the assignment is released on probe failure and driver unbind.
