Google Chrome DevTools: Memory corruption allows sandbox code execution
Summary
A memory corruption flaw in the DevTools component of Google Chrome allows a remote attacker to execute arbitrary code inside the browser sandbox. The attack is triggered by a crafted HTML page that a user must open. Sandbox-only code execution usually needs to be chained with a second flaw to fully compromise a system, but the impact is rated high for confidentiality, integrity and availability (CVSS 3.1 8.8).
Affected
- Google Chrome prior to 156.0.8078.47 (per the CVE description)
- VulDB describes affected versions up to 155.0.8059.84 (differs from the CVE description)
- Microsoft Edge and other Chromium-based products that include the affected Chromium code (HKCERT lists Edge prior to 156.0.4314.42)
Fixed in
- Google Chrome 156.0.8078.47 (Linux, Android)
- Google Chrome 156.0.8078.47 or 156.0.8078.48 (Windows, macOS)
- Version strings are taken from secondary sources and should be verified against the Chrome Releases advisory.
Workaround
Unknown. No vendor-recommended workaround was found; updating the browser is the remedy.
Exploitation
- No in-the-wild exploitation was found in the sources reviewed.
- No public proof of concept was found.
- CISA KEV status for this CVE has not been verified.
- CISA SSVC assessment: Exploitation none, Automatable no, Technical Impact total.
Our recommendation
- Inventory all Chrome and Edge installations and confirm they run version 156.0.8078.47 or later (156.0.8078.48 or later on Windows and macOS).
- Restart browsers after the update, since old processes can keep running after a staged rollout.
- Prioritise endpoints used to browse untrusted websites.
- Monitor the Chrome Releases page for follow-up updates.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
