Description
CVE-2023-2136 is a critical integer overflow vulnerability in the Skia graphics library used by Google Chrome versions prior to 112.0.5615.137. This flaw allows a remote attacker who has already compromised the renderer process to potentially escape the browser's sandbox by crafting a malicious HTML page. The vulnerability impacts confidentiality, integrity, and availability with a high CVSS score of 9.6, indicating critical severity. Exploitation requires user interaction but no prior privileges or authentication. Although no known exploits are currently reported in the wild, the risk of sandbox escape makes this a significant threat. European organizations using vulnerable Chrome versions are at risk, especially those with high exposure to web-based threats.
