About this tag
The alsa security tag covers Linux kernel vulnerabilities affecting the Advanced Linux Sound Architecture and related audio drivers. Recent coverage examines CVE-2026-64001, a use-after-free flaw in the legacy OSS compatibility layer involving PCM configuration and procfs handling, along with CVE-2026-64133, an out-of-bounds access issue in the AudioScience ASI professional audio driver. These reports focus on the fixes, affected code paths, locking and bounds-checking improvements, and the practical importance of patching. Exposure is especially relevant to organizations running Linux-based broadcast, radio, production, telephony, or specialist audio systems, while most Windows PC users are unlikely to be directly affected.
