Bug report

Bug description:

I already opened a bug on urllib3 for this issue, it looks that may application using MSAL for Python library (which relies on requests , which relies on urllib3, which relies on ssl) is leaking memory when being upgraded from Python 3.13 to Python 3.14 (I tested 3.14.{0, 1, 2})

The details are explained in the urllib3 ticket including outputs from memray and it points to ssl package (precisely ssl.SSLContext.load_verify_locations), see: urllib3/urllib3#3738

CPython versions tested on:

3.14

Operating systems tested on:

Linux
