CVE-2026-112992· CVE.org (no NVD analysis yet)· CNA Chrome

Memory corruption in Canvas in Google Chrome prior to 156.0.8078.47 allowed a remote attacker to potentially execute arbitrary code outside

Noroxi assessment

Priority: Monitor (action score 38/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.45% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: Microsoft Edge (Chromium-based) 156.0.4314.42.

Low priority for now. Upgrade to Microsoft Edge (Chromium-based) 156.0.4314.42 or later.
