Google Chrome: Use-after-free in SVG handling allows code execution
Summary
A use-after-free flaw (CWE-416) in the SVG handling of Google Chrome before 154.0.8037.97 lets a remote attacker execute arbitrary code inside the browser sandbox. The attack requires only that a user loads a crafted HTML page, for example through a phishing link or a compromised website. Full system compromise would normally need a further sandbox escape, which the sources do not confirm.
Affected
- Google Chrome desktop versions prior to 154.0.8037.97 (Windows, Linux)
- Google Chrome desktop on macOS prior to 154.0.8037.98 (the vendor advisory names .98 for macOS; treat .98 as the minimum until Google clarifies)
- Chromium-based packages from distributions (e.g. Debian, SUSE) are tracked separately under their own versions
Fixed in
- Google Chrome 154.0.8037.97 or later (Windows, Linux)
- Google Chrome 154.0.8037.98 or later (macOS)
- Later builds of the current stable channel are available; deploy the newest stable build
Workaround
- None known. Updating is the only confirmed remedy.
- For managed fleets, the Extended Stable channel also receives security fixes as a slower but supported option.
Exploitation
- No evidence of in-the-wild exploitation found in the sources reviewed. CISA SSVC lists exploitation as none; the CISA KEV catalogue was not checked directly.
- No public proof of concept found.
- Tenable has published a scan check for detection.
Our recommendation
- Inventory Chrome versions on all endpoints, including macOS (minimum .98) and Linux.
- Confirm that automatic updates are enabled, or push the current stable build through managed deployment.
- Include other Chromium-based browsers and Debian/SUSE packages in the same check.
- Verify the update after rollout and restart the browser to activate it.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
