Google Chrome: Memory corruption in PictureInPicture
Summary
Memory corruption in the PictureInPicture component of Google Chrome desktop allows a remote attacker to potentially execute arbitrary code inside the browser sandbox. The attacker needs a user to open a crafted HTML page. NVD and Microsoft rate the issue CVSS 8.8 (High), and Chromium rates it High. No exploitation in the wild was found in the sources checked.
Affected
- Google Chrome desktop builds before 156.0.8078.47
- Chromium-based browsers such as Microsoft Edge use the same code; check their vendor advisories
- Android: unconfirmed
Fixed in
- Google Chrome 156.0.8078.47 or later (Windows and macOS builds may show .48); deploy the latest 156 stable build
- Verify the exact fixed build in Google's advisory, which could not be fully reviewed
Workaround
- No workaround needed where the patch is applied. Update and restart the browser.
Exploitation
- No evidence of in-the-wild exploitation found. No public proof-of-concept found. CISA SSVC: exploitation none, automatable no.
- Treat the status as unknown rather than confirmed absent.
Our recommendation
- Update Google Chrome and Chromium-based browsers such as Microsoft Edge to 156.0.8078.47 or later, preferably the latest 156 stable build.
- Restart browsers after updating and verify the version on all desktops.
- Prioritise machines where the browser is rarely restarted.
