In the Linux kernel, the following vulnerability has been resolved:
net: lapbether: fix issue of invalid opcode in lapbeth_open()
If lapb_register() failed when lapb device goes to up for the first time,
the NAPI is not disabled. As a result, the invalid opcode issue is
reported when the lapb device goes to up for the second time.
The stack info is as follows:
