CVE-2024-58249Network attack vector

Application crash via premature event-handler deletion

Published Apr 16, 2025 · Updated Apr 17, 2025

Premature resource release in wxWebRequestCURL in wxWidgets before 3.2.7 allows remote attackers to crash affected applications. The socket poller deletes a wxEventLoopSourceHandler while a write notification is still being processed, so a following error notification accesses the released handler. The affected application must initiate a libcurl-backed web request whose connection is refused; the resulting impact is a process crash.
