I was fuzzing the TLS subsystem when I found the crash. And yes the code is in-tree.

Aah, my bad. Added it to CC.

As this seems to be fixed in 6.19, and you don't have a reproducer,
there's not much we can do here, sorry.

If you do end up with a reproducer, can you submit a backported patch to
stable@vger so that we can queue up the fix for the older kernels?

Note, they didn't get any of the previous context :(

Okay, the issue is very likely there then.  Once you find a reproducer,
you'll need to report it to the maintainers of net/tls/.
