Google Chrome: Memory corruption in Media allows sandboxed code execution
Summary
Google Chrome on Windows prior to 156.0.8078.47 contains a memory corruption flaw in the Media component (CWE-119). A remote attacker can execute arbitrary code inside the browser sandbox by luring a user to a crafted HTML page. No authentication is required, but the user must open the page. Chromium rates the issue Medium; the CVSS 3.1 base score is 8.8.
Affected
- Google Chrome on Windows prior to 156.0.8078.47
Fixed in
- Fixed in Google Chrome 156.0.8078.47 or later, according to the NVD description.
- The exact fixed build could not be confirmed from the vendor advisory; verify it against the Chromium bug 532939000 or the Chrome release notes.
Workaround
Unknown.
Exploitation
- No evidence of in-the-wild exploitation found.
- No public proof of concept found.
- A third-party tracker lists the CVE as not in CISA KEV; verify directly against the KEV catalogue.
Our recommendation
- Update Google Chrome on all Windows endpoints to the newest Chrome 156 stable build, not only 156.0.8078.47.
- Check the Microsoft Edge version separately, since Edge (Chromium) also ingests this fix.
- Enable automatic browser updates and confirm the installed versions across the fleet.
- Treat this as an urgent browser update rather than a routine patch.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
