CVE-2026-89944

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A reference count leak occurs in the ASOC hdac hda component. The hdac hda dev probe() function acquires an HDA link using snd hdac ext bus link get() before registering the ASoC component. If the registration process fails, the function returns without releasing the link reference, leading to a memory or resource leak.

Recommendations Ensure that snd hdac ext bus link put() is called after the registration attempt to balance the reference taken during the probe process, regardless of whether the registration succeeded or failed.
