Type:
security
Severity:
Critical
Release date:
2026-10-09 07:44:29 UTC
Description:
- CVE-2026-19445: use-after-free of a server-side SSLContext when the servername callback switches SSLSocket.context. _servername_callback now takes strong references to the socket's current context and its callback instead of a borrowed SSL_CTX servername arg, and context_dealloc unregisters the callback.
CVEs fixed:
