Description
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.

Executive Summary

This vulnerability in the Linux kernel involves the MT8192 ASoC driver failing to release reserved memory when the driver is cleaned up. The driver initializes reserved memory but does not free it on probe failure or driver unbind, potentially causing memory leaks.

Detection Guidance

This vulnerability is specific to the Linux kernel's ASoC driver for the MT8192 platform. Detection requires checking if the mt8192 ASoC driver is loaded and if reserved memory is not being released properly. Inspect kernel logs for errors related to mt8192 or ASoC during driver initialization or cleanup. Use commands like dmesg | grep mt8192 or lsmod | grep snd_soc_mt8192 to check driver status.

Impact Analysis

This could lead to memory exhaustion on affected systems, causing performance degradation or crashes. Systems using the MT8192 ASoC driver may experience instability if the memory leak accumulates over time.

Mitigation Strategies

Apply the latest kernel patches that include the fix for this issue. If patches are unavailable, consider disabling the MT8192 ASoC driver if not in use. Monitor kernel logs for reserved memory leaks after driver unbind or system reboot. Update to a kernel version where this issue is resolved.
