CVE-2023-6345 is a high-severity integer overflow vulnerability in the Skia graphics library used by Google Chrome prior to version 119.0.6045.199. The flaw resides in Skia’s handling of crafted graphics-related input, where arithmetic on size or buffer calculations can overflow, potentially causing incorrect memory allocation or bounds computation. In the Chrome threat model described for this issue, exploitation requires an attacker to have already compromised the renderer process and then leverage a malicious file to trigger the vulnerable Skia code path. Successful exploitation can enable a sandbox escape by turning the integer overflow into memory corruption and code execution outside the renderer sandbox.
