CVE-2024-41044 Information

Description

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.
