Google Chrome: Use-after-free in Views component
Summary
A use-after-free flaw in the Views component (the browser UI toolkit) of Google Chrome allows a remote attacker to execute arbitrary code inside the sandbox. The attacker needs a victim to open a crafted HTML page, for example through a phishing link or a compromised website. Chromium rates the bug Low severity, but the CVSS base score is 8.8 (High).
Affected
- Google Chrome prior to 156.0.8078.47 (desktop)
- Chromium-based Microsoft Edge: depends on the Chromium version it uses; Edge requires its own update
- Linux distributions: chromium packages depend on the distribution (Ubuntu lists its chromium-browser package as not affected because it uses the Chromium snap)
Fixed in
- Google Chrome 156.0.8078.47 (first fixed build, Stable channel of 20 October 2026)
- Windows and macOS: 156.0.8078.48 according to a secondary source; verify against the official advisory
- Later stable builds (for example 156.0.8078.79/.80) are available; deploy the latest stable release
- Microsoft Edge and Linux distributions: install their respective updates
Workaround
Unknown. No vendor workaround is listed; installing the fixed version is the remedy.
Exploitation
- No evidence of exploitation in the wild found; not listed in CISA KEV
- No public proof of concept found; the Chromium bug tracker content could not be fully checked
- EPSS score 0.00443 (low predicted exploitation probability)
- CISA SSVC: exploitation none, automatable no, technical impact total
Our recommendation
- Update all Chrome and Chromium-based Edge installations to the latest stable release
- Update Linux distribution chromium packages or snaps
- Enforce automatic updates via managed Chrome policies and report devices below the fixed version
- Restrict risky web links through email filtering and user awareness training
- Prioritise this update despite the vendor's Low label, because browsers are internet-facing
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
