Description
A vulnerability in the Linux kernel's ASoC Mediatek mt8183 driver was resolved. The issue involved reserved memory assigned by the MT8183 AFE probe not being released on driver removal or probe failures, potentially causing resource leaks. The fix ensures reserved memory is properly released by registering a devm cleanup action. This vulnerability affects specific Linux kernel versions and has been patched.
