Description OSIDB Bzimport 2026-08-15 06:19:53 UTC 
In the Linux kernel, the following vulnerability has been resolved:

ASoC: mediatek: mt8183: Release reserved memory on cleanup

The MT8183 AFE probe can assign reserved memory with
of_reserved_mem_device_init(), but the assignment is never released on
driver removal or later probe failures.

Register a devm cleanup action so the reserved memory assignment is
released consistently, matching newer Mediatek AFE drivers.
