CVE-2025-39696 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. In the Linux kernel, the following vulnerability has been resolved: ALSA: hda: tas2781: Fix wrong reference of tasdevice_priv During the conversion to unify the calibration data management, the reference to tasdevice_priv was wrongly set to h->hda_priv instead of h->priv. This resulted in memory corruption and crashes eventually. Unfortunately it's a void pointer, hence the compiler couldn't know that it's wrong.. EPSS estimates a 0.13% chance of exploitation in the next 30 days.
