CVE-2025-13633 is a high-severity use-after-free vulnerability in the Digital Credentials component of Google Chrome. It affects Chrome versions prior to 143.0.7499.41. The flaw can be triggered via a crafted HTML page and results in a stale object being accessed after memory has been freed, creating a heap corruption condition. Available reporting indicates exploitation requires an attacker to have already compromised the renderer process; from that position, the crafted page can be used to drive the vulnerable code path in Digital Credentials. Because the bug is in a credential-handling browser component, successful exploitation may affect sensitive credential-related operations in addition to broader browser security.
