CVE-2025-31206Network attack vector

Browser crash via type-confused state handling

Published May 12, 2025 · Updated Apr 2, 2026

Type confusion in WebKit across Apple products before the listed May 2025 releases allows remote attackers to crash Safari with crafted web content. Apple identifies improper WebKit state handling but has not disclosed the confused types, code path, or state transition that misclassifies data. A user must process attacker-controlled web content, and the documented consequence is an unexpected Safari crash rather than system compromise.
