  "details" : [ "In the Linux kernel, the following vulnerability has been resolved:\nppp: reject claimed-as-LCP but actually malformed packets\nSince 'ppp_async_encode()' assumes valid LCP packets (with code\nfrom 1 to 7 inclusive), add 'ppp_check_packet()' to ensure that\nLCP packet has an actual body beyond PPP_LCP header bytes, and\nreject claimed-as-LCP but actually malformed data otherwise.", "The vulnerability was found in the Linux kernel's ppp ppp_generic.c driver, in the ppp_read() and ppp_write() functions where malformed packets were erroneously identified as LCP packets, leading to potential issues with packet handling. This flaw could potentially lead to system instability." ],
