CVE-2026-30997: n/a
An out-of-bounds read in the read_global_param() function (libavcodec/av1dec.c) of FFmpeg v8.0.1 allows attackers to cause a Denial of Service (DoS) via a crafted input.
AI Analysis
Technical Summary
This vulnerability involves an out-of-bounds read in the read_global_param() function of the AV1 decoder component (libavcodec/av1dec.c) in FFmpeg version 8.0.1. An attacker can exploit this by supplying a specially crafted input file, causing the application to read memory outside the intended buffer boundaries, resulting in a Denial of Service condition. The vulnerability is publicly disclosed but lacks a CVSS score and official remediation guidance at this time.
Potential Impact
Successful exploitation of this vulnerability results in a Denial of Service, causing the affected FFmpeg process to crash or become unstable. There is no information indicating the ability to execute arbitrary code or escalate privileges. No known exploits are reported in the wild, and the impact is limited to service disruption.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider avoiding processing untrusted AV1 video streams with FFmpeg 8.0.1 or apply any available workarounds recommended by the vendor once published.
