Google Chrome Android: Memory corruption allows code execution in sandbox
Summary
Memory corruption in the Mobile component of Google Chrome on Android allows a remote attacker to potentially execute arbitrary code inside the browser sandbox. Exploitation requires that a user opens a crafted HTML page. Google rates the Chromium security severity as Low, and the CVSS score is 8.8. Exploitation in the wild is not known.
Affected
- Google Chrome on Android prior to 156.0.8078.47
- Official CVE record lists the affected range as 156.0.8078.47 to < 156.0.8078.47, which is inconsistent with the description; verify against the vendor release notes
Fixed in
- Android fixed build: Unknown (not verified against the vendor release notes)
- Desktop: Chrome 156.0.8078.73 (refresh of 27 Oct 2026, according to a secondary source)
- Install the latest stable Chrome release for Android
Workaround
- No vendor workaround known
- Keep Chrome on Android updating automatically and verify the installed version
Exploitation
- Exploited in the wild: Not known; no vendor or CISA statement found
- Public proof of concept: Not known
- CISA KEV listing: Not found (not checked directly)
- CISA SSVC: Exploitation none, automatable no, technical impact total
Our recommendation
- Update Chrome on all Android phones and tablets to the latest stable release, prioritising unmanaged personal devices used for work
- For managed devices, confirm that the MDM policy applies browser updates
- Check the installed Chrome version on Android devices and monitor the vendor release notes for the confirmed Android fixed build
- Medium priority: no known exploitation, but the vector requires only user interaction with a crafted web page
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
