Google Chrome: Memory corruption in ANGLE allows code execution in sandbox
Summary
Google Chrome on Windows contains a memory corruption flaw in ANGLE, Chrome's graphics abstraction layer. A remote attacker can execute arbitrary code inside the browser sandbox by luring a user to a crafted HTML page. The CVE record gives no sandbox escape, so full system compromise would need a further chained exploit. The NVD and CVSS data show a score of 8.8, but third-party VulDB rates it 6.3 and the exact affected range is disputed.
Affected
- Google Chrome on Windows prior to 156.0.8078.47 (per the CVE description)
- Third-party VulDB range: Google Chrome up to 155.0.8059.84 (not vendor-confirmed)
- Linux: not affected according to Ubuntu
Fixed in
- Google Chrome 156.0.8078.47 or later on Windows (per the CVE description)
- Vendor fixed-build table not verified. Secondary sources mention 156.0.8078.48 and, unconfirmed, newer 156 builds such as 156.0.8078.79 or .80
Workaround
Unknown.
- No workaround is documented in the sources checked. Updating Chrome is the fix.
Exploitation
- No evidence of exploitation in the wild found. CISA KEV status not verified directly.
- EPSS 0.00417 (low exploitation probability)
- CISA SSVC: exploitation none, automatable no, technical impact total
- No public proof of concept known
Our recommendation
- Update Chrome on all Windows systems to the latest Chrome 156 build, not only 156.0.8078.47
- Check the official Chrome Releases blog for the exact fixed build
- Keep Chrome auto-update enabled and verify versions across the fleet, including managed deployments such as Chrome Enterprise policies
- Priority: high for Windows fleets, because the browser is exposed to web content by design
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
