Thank you much for your research. I'm happy my report
has resulted as the proposed patch.

while, I see that commit c9c3321257 just increases(?) an skb buffer(?)
(which fixes hitting the BUG() for this exact reproducer), but does not fix the
real reason (so another set of syscalls still may cause hitting the BUG()). This
is why I'm emailing not only to stable@, but also to netdev@, asking to review
" statement, unfortunately, this investigation was not
completed at
the time the patch was accepted upstream. And unfortunately I do not see other
way
to add this information except making notes in a comment in the related code,
which
seems weird.

Actually, this is so small and unimportant (it just hurts my perfectionism),
so does not worth a separate patch. Please, feel free to make it a part of
some patch of yours.

to fix it.
I hope I did not do much damage, reporting previous fix as a fix for this bug,
as syzkaller will probably create another "KMSAN: uninit-value in <...>"
report.
