Google Chrome: Use after free in Bindings allows sandboxed code execution
Summary
Google Chrome versions prior to 155.0.8059.39 contain a use-after-free vulnerability in the Bindings component (CWE-416). A remote attacker can execute arbitrary code inside the browser sandbox by luring a user to a crafted HTML page. The attack requires no privileges, but user interaction is needed (UI:R). Google rates the Chromium security severity as High and NVD scores it 8.8.
Affected
- Google Chrome prior to 155.0.8059.39
- Chromium-based browsers that include the affected Chromium code, such as Microsoft Edge, depending on their release
Fixed in
- Google Chrome Stable 155.0.8059.39 (Linux)
- Google Chrome Stable 155.0.8059.39/.40 (Windows and Mac)
- Linux distributions: chromium 155.0.8059.39 or later in their package repositories; Ubuntu uses the Chromium snap
Workaround
Unknown. No workaround found in the reviewed sources; updating is the fix.
Exploitation
- CISA SSVC: exploitation none, not automatable
- Not listed in the CISA KEV catalogue
- No public proof of concept found; Chromium bug details are restricted, so this is unknown rather than confirmed absent
- No vendor statement of in-the-wild exploitation found
Our recommendation
- Update Google Chrome and Microsoft Edge to 155.0.8059.39 or later (Windows and Mac: 155.0.8059.39/.40 or later).
- Check Linux Chromium packages and snaps against the distribution advisories.
- Verify the version on all endpoints in managed fleets, including laptops that are rarely online.
- Keep the status under review, as the Chromium bug entry is restricted and may change.

PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
