Exploitation evidence

Disclosed: evidence found.
CVE published 26 Aug 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 29 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

AI-suggested

Red Hat has released updated ffmpeg packages as part of the Red Hat Enterprise Linux AI 3.5 platform to address these vulnerabilities. Users should ensure all previously released errata relevant to their systems are applied before applying this update. The advisory provides guidance on applying the update and references Red Hat's documentation for errata application. Since these RPM packages are supported only as part of the Red Hat AI application platform, users should update the platform accordingly to remediate the vulnerabilities.

Description

This Red Hat security advisory addresses vulnerabilities in the ffmpeg component of the Red Hat Enterprise Linux AI 3.5 platform. The advisory notes that RPM packages are internal build artifacts supported only as part of the Red Hat AI application platform. The update fixes multiple CVEs, including CVE-2026-64834, CVE-2026-66036, and CVE-2026-66039, which have been assigned a severity level of Important or higher. The advisory recommends applying this update after all previously released errata relevant to the system have been applied.

Impact

The vulnerabilities affect the ffmpeg component within the Red Hat Enterprise Linux AI 3.5 platform. The severity is classified as Important or higher, indicating a significant security risk if unpatched. The exact impact details are not specified in the advisory, but the presence of multiple CVEs and the classification suggest potential risks related to memory management or runtime issues (CWE-835, CWE-787). No known exploits in the wild are reported at this time.

Summary

The advisory concerns security vulnerabilities in the ffmpeg packages used within Red Hat Enterprise Linux AI 3.5. These vulnerabilities are identified by CVE-2026-64834, CVE-2026-66036, and CVE-2026-66039. The RPM packages affected are internal build artifacts and are supported only as part of the Red Hat AI application platform. The advisory provides updated ffmpeg packages to address these vulnerabilities. No CVSS score is provided, but the severity is indicated as Important or higher. The advisory directs users to apply this update following prior errata to ensure system security.
