Google Chrome: Memory corruption in Paint allows code execution in sandbox
Summary
A memory corruption flaw in the Paint component of Google Chrome prior to 156.0.8078.47 allows a remote attacker to execute arbitrary code inside the browser sandbox. The attacker needs a crafted HTML page that the user must open, so user interaction is required. Google rates the Chromium security severity as Critical, and the NVD CVSS 3.1 base score is 8.8.
Affected
- Google Chrome (desktop) prior to 156.0.8078.47
- Chromium-based browsers and Linux distribution packages depend on their own vendor fixes; check each vendor's advisory.
Fixed in
- Google Chrome 156.0.8078.47 or later, according to the NVD description.
- Secondary sources report later Stable builds. The exact fixed build for each platform is unknown until confirmed in the primary Google advisory.
Workaround
- No workaround known. Update Chrome and restart the browser, because the update is applied only after a relaunch.
- For managed devices, enforce a minimum Chrome version through the update policy.
Exploitation
- Google reports no exploitation in the wild for this vulnerability (based on secondary sources; not confirmed in the vendor advisory).
- CISA KEV status: not confirmed in the CISA catalogue. A third-party aggregator lists it as not in KEV.
- Public proof of concept: none found.
- Bug details remain restricted in the Chromium tracker.
Our recommendation
- Update Chrome and all Chromium-based browsers to the latest Stable build now and verify the version on each endpoint.
- Ensure that browsers are restarted after the update.
- Check Linux and managed-device update channels, especially Debian and Ubuntu packages.
- Monitor the Chromium bug tracker and CISA KEV for news on exploitation.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
