Google Chrome: Use-after-free in Network component allows code execution
Summary
A use-after-free vulnerability in the Network component of Google Chrome before 156.0.8078.47 allows a remote attacker to execute arbitrary code inside the browser sandbox. The attacker needs a victim to open a crafted HTML page, so user interaction is required. The CVSS score is 8.8 (HIGH); Google rates the Chromium security severity as Medium.
Affected
- Google Chrome prior to 156.0.8078.47
- Microsoft Edge (Chromium-based): prior to 156.0.4314.42 according to a HKCERT bulletin; not verified against Microsoft's advisory
Fixed in
- Google Chrome 156.0.8078.47 or later (Windows/macOS: 156.0.8078.47 or .48 for the 20 October 2026 release; later 156 builds such as 156.0.8078.79/.80 also exist)
- Microsoft Edge 156.0.4314.42 or later (per HKCERT)
- Linux snap installs of Chromium are updated separately
Workaround
Unknown. No vendor workaround is known; updating is the remedy.
Exploitation
- No evidence of exploitation in the wild found in the research
- No public proof of concept found
- CISA SSVC assessment: Exploitation none, Automatable no, Technical Impact total
- EPSS 0.00337 at the time of the Vulners listing
Our recommendation
- Update all Chrome and Edge installations to the latest version of the 156 branch (at least 156.0.8078.47 for Chrome and 156.0.4314.42 for Edge)
- Check Linux installations that use Chromium snaps separately
- Ensure managed browser policies force a restart after updates, because Chrome applies updates only after relaunch
- Prioritise browsers used for internet access
