Description OSIDB Bzimport 2026-01-13 16:04:20 UTC 
In the Linux kernel, the following vulnerability has been resolved:

ASoC: stm32: sai: fix OF node leak on probe

The reference taken to the sync provider OF node when probing the
platform device is currently only dropped if the set_sync() callback
fails during DAI probe.

Make sure to drop the reference on platform probe failures (e.g. probe
deferral) and on driver unbind.

This also avoids a potential use-after-free in case the DAI is ever
reprobed without first rebinding the platform driver.
