Google Chrome: Memory corruption in Chromoting allows sandbox code execution
Summary
A memory corruption flaw in the Chromoting component of Google Chrome before 156.0.8078.47 can be triggered by a remote attacker using a crafted HTML page. Successful exploitation could allow arbitrary code execution inside the browser sandbox. The victim must load the crafted page, and a separate sandbox escape would be needed for full compromise. Google rates the bug Low, while the CVSS score in the NVD entry is 8.8 (High).
Affected
- Google Chrome desktop versions prior to 156.0.8078.47
Fixed in
- Google Chrome 156.0.8078.47 or later (per the CVE record)
- Latest 156.x Stable build recommended; the exact fixed build per platform could not be verified against the vendor advisory
Workaround
- None needed where patches are available.
- Without a patch: restrict browsing to trusted websites.
Exploitation
- No exploitation in the wild known.
- No public proof of concept found.
- Not listed as KEV in the sources checked; the CISA catalogue itself was not checked directly.
Our recommendation
- Update all Chrome and Edge installations to 156.0.8078.47 or later, preferably the latest 156.x build.
- Check that managed fleets and Linux repositories have received the update.
- If Chrome Remote Desktop is used, treat this update as higher priority.
- Verify that automatic browser updates are not blocked or paused.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
