Google Chrome: Use-after-free in SVG rendering
Summary
Google Chrome contains a use-after-free flaw (CWE-416) in its SVG rendering component. A remote attacker can execute arbitrary code inside the browser's renderer sandbox by luring a user to a crafted HTML page. User interaction is required, but no authentication. Google and NVD rate the issue High (CVSS 8.8).
Affected
- Google Chrome versions prior to 155.0.8059.79
- Desktop builds for Windows, macOS and Linux
Fixed in
- Windows and macOS: 155.0.8059.79 or 155.0.8059.80
- Linux: 155.0.8059.79
- Android: sources conflict (155.0.8059.79 or 155.0.8059.84 on Google Play); check the installed build
- Debian bookworm: 155.0.8059.79-1~deb12u1
- Ubuntu: updates are delivered via Snap
Workaround
- No workaround; apply the browser update.
- Until patched, limit browsing of untrusted sites and keep browser extensions to a minimum.
Exploitation
- Not confirmed in the wild according to one secondary source; not verified in Google's advisory.
- Not listed in CISA KEV.
- No public proof of concept found.
- CISA SSVC: exploitation none, automatable no, technical impact total.
Our recommendation
- Verify that all Chrome installations are at 155.0.8059.79 or later, preferably the current stable release.
- Enforce automatic updates via endpoint management and check versions on Windows, macOS, Linux and Android.
- Restrict browsing of untrusted sites and minimise extensions until patched.
- Rate as High for your environment.
