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: [ 1958.311422][T11356] kernel BUG at net/core/dev.c:6442!
