LinuxVULNRICHMENT:CVE-2024-41044CVE-2024-41044 ppp: reject claimed-as-LCP but actually malformed packets
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.
