Google Chrome: Memory corruption in Browser component
Summary
Google Chrome versions before 156.0.8078.47 contain a memory corruption flaw (CWE-119) in the Browser component. A remote attacker can use a crafted HTML page to potentially execute arbitrary code inside the browser sandbox. The victim must open the malicious page, and no authentication is required.
Affected
- Google Chrome on Linux: prior to 156.0.8078.47
- Google Chrome on Windows and macOS: prior to 156.0.8078.47/.48
- Note: the official CVE record lists an inconsistent range (156.0.8078.47 to < 156.0.8078.47).
Fixed in
- Linux: 156.0.8078.47
- Windows and macOS: 156.0.8078.47/.48
- Later stable builds (156.0.8078.79/.80 on Windows and macOS, 156.0.8078.79 on Linux, according to Techspot) are on the same branch. The vendor advisory does not explicitly confirm them.
Workaround
Unknown. No vendor workaround is documented. Not required where a patched build is installed.
Exploitation
- No in-the-wild exploitation known at the time of analysis.
- CISA SSVC assessment: Exploitation none, Automatable no, Technical Impact total.
- No public proof of concept found.
Our recommendation
- Update Google Chrome to the latest 156 stable build and verify the version number on each workstation.
- Include Microsoft Edge and other Chromium-based browsers in the same check, as they receive the upstream fix.
- Enable automatic browser updates where possible and monitor the Chrome release channel.
- Restrict browsing to trusted sites on unpatched devices until the update is installed.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
