Google Chrome: Improper input validation in ANGLE graphics component
Summary
Improper input validation in the ANGLE graphics component of Google Chrome on Windows allows a remote attacker to potentially execute arbitrary code inside the browser sandbox. The attack requires the user to open a crafted HTML page. Code execution inside the sandbox is limited, so a full compromise usually also needs a second sandbox-escape flaw.
Affected
- Google Chrome on Windows prior to 156.0.8078.47
- The CNA record's parsed version range is inconsistent; rely on the description text.
Fixed in
- Google Chrome 156.0.8078.47 (CNA description); the vendor release lists 156.0.8078.47 and .48 for Windows and Mac.
- Target: 156.0.8078.48 or later on Windows.
Workaround
- No vendor workaround known. Installing the update is the fix.
- Until patched, limit browsing to trusted sites.
Exploitation
- No evidence of exploitation in the wild; CISA KEV not listed.
- CISA SSVC: exploitation none, automatable no, technical impact total.
- No public proof-of-concept found.
- EPSS about 0.0044 (low).
- Root cause details are unknown (Chromium bug 564064199 not accessible).
Our recommendation
- Inventory Chrome and Edge (Chromium) versions on Windows endpoints.
- Deploy Chrome 156.0.8078.48 or later, as part of the full Chrome 156 release.
- Confirm the browser has restarted after the update.
- Enforce automatic updates via Chrome or Windows policy.
- Plan around the CVSS 8.8 score until NVD confirms the rating.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
