[kworker/u16 Not tainted]

kernel panic is occuring in up-to-date net-next kernel as well as with 
ALL kernels since linux-6.15.1

As shown in attached picture Oops is always correlated with mkiss.

mkiss driver is used in hamradio communications and in this specific 
case it is associated with AX25 and rose drivers in fpac a ROSE/FPAC 
network application.

The bug is trigger by a connect request in fpac to a neighbour node 
using axudp device created by ax25ipd for IP encapsulation over AX25 frames.
