CVE-2025-39696

MEDIUM

Linux Kernel 6.16-6.16.3 - Memory Corruption via Incorrect tasdevice_priv Reference

Title source: llm

Description

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.
