Log message:
cherrypick fix for CPython CVE-2026-19445: Use-after-free of a
server-side SSLContext when sni_callback switches contexts. ok tb kmos
A remote, unauthenticated TLS client can make a server crash or call
through a freed pointer if its sni_callback assigns a different context
to SSLSocket.context (the documented way to select a certificate per
server name) and nothing else keeps the original ssl.SSLContext alive.
Typical cases are servers that create an SSLContext per connection or
replace it while connections are open.
