Google Chrome: Memory corruption in Video component
Summary
A memory corruption flaw in the Video component of Google Chrome before 156.0.8078.47 may allow a remote attacker to execute arbitrary code inside the browser sandbox. The attack requires that a user opens a crafted HTML page, for example via a link in an email or an advertisement. The CVE record does not describe a sandbox escape. Chromium rates the issue Medium, and the CVSS base score of 8.8 comes from the input data and could not be confirmed on NVD.
Affected
- Google Chrome desktop builds prior to 156.0.8078.47
- Chromium-based browsers that include the affected Chromium code (for example Microsoft Edge), until they are updated
- The CVE record lists the affected range inconsistently, so the vendor release notes should be checked for exact versions
Fixed in
- Google Chrome 156.0.8078.47 or later (version taken from secondary sources; confirm on the Google release page)
- Linux distributions: check the vendor advisories for Chromium packages
- Ubuntu: the chromium-browser package installs the Chromium snap, so check the snap channel directly
Workaround
- Unknown. No vendor-documented workaround was found.
- Until patched, restrict browsing on unpatched systems and block untrusted links (general advice, not a vendor recommendation).
Exploitation
- No evidence found of exploitation in the wild or of a public proof of concept.
- Not listed in CISA KEV at the time of research; verify directly in the CISA KEV catalogue.
- CISA SSVC assessment: exploitation none, not automatable, total technical impact.
Our recommendation
- Update Google Chrome (and other Chromium-based browsers) to a fixed version on all desktop systems.
- Fully restart the browser after the update, because the old process may still run.
- Check the installed version on all workstations and monitor for updates from the browser vendor.
- Until patched, avoid untrusted links and websites.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
