Google Chrome: Improper input validation in Skia graphics library
Summary
Improper input validation in the Skia graphics library of Google Chrome before 156.0.8078.73 allows a remote attacker to potentially execute arbitrary code inside the browser sandbox. The attacker needs to lure a user to a crafted HTML page; no authentication is required. Chromium rates the issue Critical, and NVD assigns CVSS 8.8.
Affected
- Google Chrome desktop prior to 156.0.8078.73 (per NVD/CNA description)
- VulDB lists the range up to 156.0.8078.47; the exact lower bound is unconfirmed.
Fixed in
- Google Chrome 156.0.8078.73 or later (per NVD/CNA description)
- Secondary sources report newer Stable builds 156.0.8078.79/.80 (Windows and macOS) and 156.0.8078.79 (Linux); deploy the newest Stable build.
Workaround
Unknown. No vendor-recommended workaround was found; apply the browser update.
Exploitation
- No evidence of exploitation found.
- Not listed in CISA KEV according to third-party trackers; verify directly in the KEV catalogue.
- No public proof-of-concept found as of 26 Oct 2026.
- CISA SSVC: Exploitation none, Automatable no, Technical Impact total.
Our recommendation
- Update all desktop Chrome installations to the newest Stable build and verify versions across the fleet.
- Update Chromium-based browsers that use the same Skia code.
- Ensure users relaunch the browser after the update, as Chrome may otherwise keep running the old version.
- Enforce browser updates through your management tooling.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
