Google Chrome: Memory read via ANGLE memory corruption in crafted HTML page
Summary
A memory corruption flaw in ANGLE, the graphics translation layer of Google Chrome, allows a remote attacker to read process memory. The attacker needs the victim to open a crafted HTML page in a vulnerable browser. The vendor rates the Chromium severity as Medium, and the CVSS base score is 8.8 according to the CNA; the impact described is confidentiality, not code execution.
Affected
- Google Chrome versions before 156.0.8078.47
- Microsoft Edge builds based on affected Chromium versions (check Microsoft's advisory for exact builds)
- Unknown: exact affected Edge build range and Linux package status beyond Ubuntu's snap-based chromium packages
Fixed in
- Google Chrome 156.0.8078.47 and later (per secondary source; rollout may vary by platform)
- Microsoft Edge: fixed build per Microsoft's advisory (unknown in this entry)
Workaround
Unknown. No workaround found; updating is the fix.
Exploitation
- No evidence of exploitation in the wild found; not listed in CISA KEV at the time of the tracker entry
- EPSS very low (0.22% in one tracker)
- No public proof-of-concept found in searches (not exhaustively checked)
- CISA SSVC: exploitation none, not automatable, partial technical impact
Our recommendation
- Update Google Chrome and Microsoft Edge to 156.0.8078.47 or later (or the Edge build from Microsoft's advisory) on all endpoints
- Verify that automatic updates work on managed devices and enforce updates via your management tool where possible
- Patch the whole Chrome 156 release, which fixes further security issues
- Check Chromium-based browsers in use and verify the installed version after the update
- Recheck NVD for the final CVSS score once analysis is complete
