Google Chrome: Improper input validation in Skia graphics library
Summary
Google Chrome versions before 156.0.8078.73 contain an input validation flaw in Skia, Chrome's graphics library. A remote attacker can use a crafted HTML page to potentially execute arbitrary code inside the browser sandbox. The victim must open the malicious page, for example through a link or email, and no privileges are required. The description does not claim a sandbox escape.
Affected
- Google Chrome before 156.0.8078.73 (desktop)
- The official CVE record lists the affected range inconsistently, so verify the version against the vendor advisory.
Fixed in
- Google Chrome 156.0.8078.73 or later (Stable desktop update of 27 Oct 2026; Windows and Mac 156.0.8078.73/.74 according to secondary reports, Linux 156.0.8078.73)
- Separate Skia bug CVE-2026-119261 is fixed in 156.0.8078.79, so deploy the latest stable build.
- Extended Stable (ESR) fix: Unknown.
Workaround
- No vendor workaround known. The fix is the update.
- Other mitigations: Unknown.
Exploitation
- No known exploitation in the wild as of 31 Oct 2026 according to the available data.
- No public exploit known (OffSeq data as of 26-27 Oct 2026).
- Not listed in CISA KEV according to a GitHub alert (snapshot date unknown).
- CISA SSVC: Exploitation none, Automatable no, Technical Impact total.
- EPSS: 0.26 % (percentile 18).
- Chromium issue tracker status: Unknown.
Our recommendation
- Update Google Chrome to 156.0.8078.73 or later, and to the latest stable build.
- Enforce a minimum browser version through managed update policies.
- Check the installed version on all endpoints (chrome://version).
- Make sure browsers are restarted after the update, because the update is not complete until then.
- Prioritise endpoints that browse untrusted sites or receive external links.
- Recheck CISA KEV and vendor information before closing the item.

PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
