Hello,

gnutls 3.7.3-4ubuntu1.1 does not properly check for AVX support. On VMs
that disable AVX / XSAVE but still set the AVX cpuid capability
processes that use gnutls are crashing with an illegal instruction
error.

For details see:
https://gitlab.com/gnutls/gnutls/-/issues/1282#note_991427169

Attached you'll find the debdiff which adds 
https://gitlab.com/gnutls/gnutls/-/commit/8ff391fa011e02c88b0d099061ca62e88ab68011

I locally built the package and verified that the error on my VM is gone. Please consider including this patch into jammy. Upstream acknowledged that this patch is sufficient to fix the bug:

Thanks,
