[ Upstream commit 17ad73e941b71f3bec7523ea4e9cbc3752461c2d ]
We recently added some bounds checking in ax25_connect() and
ax25_sendmsg() and we so we removed the AX25_MAX_DIGIS checks because
they were no longer required.
Unfortunately, I believe they are required to prevent integer overflows
so I have added them back.
Fixes: 8885bb0621f0 ("AX.25: Prevent out-of-bounds read in ax25_sendmsg()")
Fixes: 2f2a7ffad5c6 ("AX.25: Fix out-of-bounds read in ax25_connect()")
