Google Chrome: Memory corruption in Extensions
Summary
Google Chrome for desktop before 156.0.8078.47 contains a memory corruption flaw in its Extensions component (CWE-119). A remote attacker who lures a user to a crafted HTML page could potentially execute arbitrary code inside the browser sandbox. The impact is limited to the sandbox, so a full system compromise would require an additional sandbox escape. Exploitation needs no login but requires the victim to visit the malicious page.
Affected
- Google Chrome desktop builds prior to 156.0.8078.47 (per CNA/NVD record)
- Scoring differs: NVD lists CVSS 8.8, VulDB 6.3, Chromium rates it Medium.
Fixed in
- Google Chrome 156.0.8078.47 or later (first fixed build per CNA record)
- Microsoft Edge 156.0.4314.42 or later (per HKCERT bulletin, verify with Microsoft)
- Linux distributions and snap packages: Unknown, verify the package version.
Workaround
Unknown. No vendor workaround identified; updating is the remedy.
Exploitation
- No evidence of exploitation in the wild found.
- CISA SSVC: Exploitation none, Automatable no, Technical Impact total.
- No public proof of concept found; not confirmed by a primary source.
Our recommendation
- Confirm all Chrome and Edge installations run the newest stable build of their channel, at least 156.0.8078.47.
- Check Linux and snap installations as well.
- Enforce automatic updates via group policy or the Chrome Enterprise console.
- Monitor the vendor advisory for updates on exploitation status.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
