In the Linux kernel, the following vulnerability has been resolved: ASoC: mediatek: mt8192: Release reserved memory on cleanup The MT8192 AFE probe calls of_reserved_mem_device_init() 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.

A flaw was found in the Linux kernel's ASoC (Audio System on Chip) Mediatek MT8192 audio driver. This vulnerability occurs because the driver fails to release reserved memory after a successful assignment during the probe process. This oversight can lead to a memory leak, potentially causing system instability or a Denial of Service (DoS) due to resource exhaustion over extended operation.
