Google Chrome: Memory corruption in Workers allows code execution in sandbox
Summary
Google Chrome versions before 155.0.8059.84 contain a memory corruption flaw in the Workers component (CWE-119). A remote attacker can potentially execute arbitrary code inside the browser sandbox by luring a user to a crafted HTML page. The official record limits the impact to the sandbox; a full compromise would likely also need a sandbox escape, which is not documented.
Affected
- Google Chrome prior to 155.0.8059.84 (Windows, macOS, Linux)
- Chromium-based browsers (e.g. Edge, Brave, Opera) may be affected; their versions are unknown
- Ubuntu chromium-browser (Snap) is listed as not affected
- The NVD version range is inconsistent; use the Chrome advisory as reference
Fixed in
- Google Chrome 155.0.8059.84/.85 for Windows and macOS
- Google Chrome 155.0.8059.84 for Linux
- Stable channel update of October 15, 2026; rollout is ongoing
- Debian and Fedora chromium packages reference this CVE; package versions were not verified
Workaround
Unknown. No vendor workaround is documented; apply the update.
Exploitation
- No exploitation in the wild reported
- Not listed in CISA KEV
- CISA Vulnrichment: exploitation none, automatable no
- No public proof of concept found in the research
Our recommendation
- Update Google Chrome and all Chromium-based browsers to 155.0.8059.84 or later (155.0.8059.84/.85 on Windows and macOS)
- Restart browsers after the update; enforce this in managed fleets
- Check Linux distribution packages (Debian, Fedora) and Snap-based Chromium separately
- Bundle this update with the other October 2026 Chrome fixes, including the Critical Prerender bug CVE-2026-110922
- Monitor CISA KEV and the Chromium issue tracker for changes in exploitation status
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
