Integer overflow in Skia in Google Chrome prior to 148.0.7778.216 allowed a remote attacker who had compromised the renderer process to pote

Noroxi assessment

Priority: Monitor (action score 33/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.18% (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. Special conditions such as timing or configuration are required.
  • Fixed version: Microsoft Edge (Chromium-based) 148.0.3967.96.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Microsoft Edge (Chromium-based) 148.0.3967.96 or later.
