What to do
AI-suggested
A fix for this vulnerability has been implemented in the Linux kernel. Users should apply the official kernel updates that address this issue. Since the vulnerability is limited to root users via debugfs, restricting root access and applying the patch are effective mitigations.
Description
CVE-2025-38317 is a high-severity buffer overflow vulnerability in the Linux kernel's ath12k Wi-Fi driver debugfs interface. Writing more than 32 bytes to this debugfs entry causes memory corruption. The vulnerability is limited to users with root privileges because debugfs access requires elevated permissions.
