CVE-2026-89944

CVE-2026-89944 is a reference-count leak in the Linux kernel's ASoC hdac_hda driver. In hdac_hda_dev_probe(), an HDA link reference is acquired via snd_hdac_ext_bus_link_get() before registering the ASoC component. If component registration fails, the function returns without calling snd_hdac_ext...
