CVE-2024-50033

CVE-2024-50033 is a Linux kernel issue in the SLIP driver (drivers/net/slip/slhc.c). The root cause was that slhc_remember() did not adequately validate malicious packets, only checking that the packet length was at least 20 bytes. This allowed malformed frames to slip through without ensuring th...
