Google Chrome: Memory corruption in Extensions allows code execution in sandbox
Summary
Google Chrome before 156.0.8078.47 contains a memory corruption flaw in its Extensions component (CWE-119). A remote attacker can execute arbitrary code inside the browser sandbox by luring a user to a crafted HTML page. Chromium rates the issue Medium, and no exploitation in the wild is known.
Affected
- Google Chrome before 156.0.8078.47
- Chromium-based browsers that ingest the fix, such as Microsoft Edge, depending on their release
- Note: the CVE record's affected range is inconsistent ("156.0.8078.47 to < 156.0.8078.47"); the description implies builds before 156.0.8078.47
Fixed in
- Google Chrome 156.0.8078.47 (Linux)
- Windows and macOS: 156.0.8078.47 or 156.0.8078.48 (the exact build containing this fix is unverified)
- Android: 156.0.8078.47
- Debian and Ubuntu packages: see the distribution trackers; Ubuntu lists its chromium-browser package as not affected because it is a Snap wrapper
Workaround
Unknown. No vendor workaround is documented, since a patched build is available.
Exploitation
- No evidence of in-the-wild exploitation found; not listed in CISA KEV.
- No public proof-of-concept found.
- CISA SSVC: exploitation none, automatable no, technical impact total.
- Chromium severity: Medium.
Our recommendation
- Update Chrome and Chromium-based browsers such as Edge to the fixed builds through managed deployment.
- Confirm the installed version on every endpoint and restart the browser so the fix applies.
- Verify the CVSS 8.8 score on NVD, as some aggregators still show the CVE as unscored.
- Review installed browser extensions and remove unneeded ones.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
