A bogus test in b_get_varint(), b_put_varint(), b_peek_varint() shifts the end of the buffer by one byte. Since the bug is the same in the read and write functions, the buffer contents remain compatible, which explains why this bug was not detected earlier. But if the buffer ends on an aligned address or page, it can result in a one-byte overflow which will typically cause a crash or an inconsistent behavior. This API is only used by rings (e.g. for traces and boot messages) and by DNS responses, so the probability to hit it is extremely low, but a crash on boot was observed. This must be backported to 2.2.
