CVE-2026-38350: 
Ffmpeg vulnerability analysis and mitigation

CVE-2026-38350 is an integer overflow vulnerability in FFmpeg's target_sws_fuzzer() function located in libswscale/output.c. It affects FFmpeg version N-122528-gdd2976b9e1 and allows unauthenticated remote attackers to cause a Denial of Service (DoS) by supplying crafted input. The vulnerability was published on August 28, 2026, and carries a CVSS v3.1 base score of 7.5 (High) (Github Advisory, Red Hat Bugzilla).

The root cause is an integer overflow or wraparound (CWE-190) in the target_sws_fuzzer() function within FFmpeg's libswscale/output.c. When processing crafted input, an integer calculation produces a value that exceeds the representable range, causing the value to wrap around to a very small or negative number, which can lead to a crash. The attack vector is network-based, requires no authentication or user interaction, and has low attack complexity, making it straightforward to trigger remotely. The vulnerability was identified via fuzzing, as indicated by the function name target_sws_fuzzer() and the FFmpeg bug tracker reference (Github Advisory, FFmpeg Ticket).

Successful exploitation results in a Denial of Service, crashing the FFmpeg process. There is no impact on confidentiality or data integrity — the vulnerability is limited to availability. Services or applications that rely on FFmpeg for media processing (e.g., transcoding pipelines, streaming servers) could be disrupted by an attacker supplying malicious media input (Github Advisory, Red Hat Bugzilla).

There is no public proof-of-concept exploit and no evidence of in-the-wild exploitation at this time. The EPSS score is approximately 0.149% (Feedly data) to 0.324% (GitHub Advisory), indicating a low probability of exploitation in the near term. The NVD SSVC assessment classifies exploitation as "none" and the technical impact as "partial." No threat actor attribution or CISA KEV catalog listing has been identified (Github Advisory).

No specific patched version has been publicly identified yet; the GitHub Advisory Database lists affected and patched versions as "Unknown." Organizations should monitor the FFmpeg project's official bug tracker (ticket #11686) and release announcements for a fix. In the interim, consider restricting access to FFmpeg-based processing services, implementing input validation and sanitization for media inputs, and avoiding processing untrusted media files with the affected FFmpeg build (N-122528-gdd2976b9e1) (Github Advisory, FFmpeg Ticket, Red Hat Bugzilla).

Red Hat has opened a security tracking bug (Bug 2525313) and assigned it medium priority and severity, indicating it is being monitored for impact on Red Hat products. No notable public researcher commentary or significant media coverage has been identified beyond standard vulnerability database entries (Red Hat Bugzilla).
