What it is

In the Linux kernel, the following vulnerability has been resolved:

ppp: reject claimed-as-LCP but actually malformed packets

Since 'ppp_async_encode()' assumes valid LCP packets (with code

from 1 to 7 inclusive), add 'ppp_check_packet()' to ensure that

LCP packet has an actual body beyond PPP_LCP header bytes, and

reject claimed-as-LCP but actually malformed data otherwise.
