Google Chrome: Use after free in Chromoting component
Summary
A use-after-free vulnerability in the Chromoting component of Google Chrome allows a remote attacker to execute arbitrary code inside the browser sandbox. The attack requires a victim to open a crafted HTML page. Chromium rates the issue as low severity, and CISA SSVC assessments show no exploitation and no automatable attack path.
Affected
- Google Chrome desktop builds prior to 156.0.8078.47 (according to the CVE description)
- Secondary reports list 156.0.8078.47 or 156.0.8078.48 as fixed on Windows and macOS; the vendor advisory could not be verified directly
- Microsoft Edge: secondary reports list versions prior to 156.0.4314.42 as affected (not verified on MSRC)
Fixed in
- Google Chrome 156.0.8078.47 or later (Linux, Windows and macOS; some Windows and macOS users receive 156.0.8078.48)
- Debian has released chromium updates (DSA 6577-1, DLA 4853-1)
- Ubuntu lists the chromium-browser package as not affected because it ships as a snap; check the snap revision
Workaround
Unknown.
Exploitation
- No known exploitation in the wild
- No public proof of concept found
- CISA SSVC: exploitation none, not automatable, total technical impact
Our recommendation
- Update Google Chrome to version 156.0.8078.47 or later on all desktop and Android systems
- Check the Chrome version on all managed devices and verify automatic updates are enabled
- On Ubuntu systems, check the snap revision of the chromium browser
- Confirm the Microsoft Edge fix on the MSRC update guide if Edge is in use
