Summary
python2: Fix of CVE-2026-19445
Details
  • CVE-2026-19445: fix a use-after-free in the SNI servername callback by taking the SSLContext from the live socket, with a strong reference, instead of the borrowed pointer registered on the SSL_CTX, and by unregistering the callback in context_dealloc, so a context released after the callback has switched the connection to another context can no longer be reached through the connection's session_ctx
