Google Chrome: Use-after-free in Input allows code execution in sandbox
Summary
A use-after-free flaw in the Input component of Google Chrome allows a remote attacker to execute arbitrary code inside the browser sandbox. The attacker needs a victim to open a crafted HTML page, for example via a phishing link or a compromised website. The CVE data does not describe a sandbox escape, so full system compromise would require an additional step. The CVSS base score is 8.8 (High).
Affected
- Google Chrome prior to 156.0.8078.47 (CVE record).
- VulDB lists the affected range as up to 155.0.8059.84 (secondary source).
- Ubuntu lists its chromium-browser deb packages as not affected; Ubuntu ships Chromium as a snap, so check the snap version.
Fixed in
- Chrome 156.0.8078.47 or later (CVE record).
- Secondary reports list 156.0.8078.48 for Windows and macOS. Verify against the Google Chrome Releases post, which was not read directly.
Workaround
- No workaround is known. Update Chrome.
- Restart the browser after updating, because the old binary may keep running until relaunch.
Exploitation
- Exploited in the wild: Unknown. Not listed in CISA KEV according to a secondary source.
- Public proof of concept: none found.
- CISA SSVC assessment: exploitation none, not automatable, total technical impact.
Our recommendation
- Update Chrome on all desktops, including Linux, macOS and Android, to the fixed builds within days.
- Check the running version on each device and enforce a minimum version via the update policy or MDM.
- Restart the browser after the update.
- Keep the operating system and other software current, because browser flaws are often the first stage of an attack chain.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
