CVE-2024-24861

System crash via unlocked frequency-state reads

Published Feb 5, 2024 · Updated Feb 13, 2025

Race condition in the Linux kernel XC4000 tuner driver before 6.8-rc1 allows local users to crash the system during frequency access. xc4000_get_frequency reads priv->freq_hz and priv->freq_offset without the mutex while xc4000_set_params can update them concurrently, yielding an inconsistent sum. Reachability requires local low-privileged access, user interaction, and an XC4000 tuner using the driver; impact is limited to incorrect frequency behavior or a system crash.
