kernel: udp: Fix wildcard bind conflict check when using hash2

A flaw was found in the Linux kernel's User Datagram Protocol UDP implementation. When a significant number of UDP sockets are bound to specific local addresses on the same port, the kernel's conflict detection mechanism can fail. This allows a local attacker to bind to a wildcard address on a po...

CVE-2026-67277: Missing Authentication for Critical Function

RouterOS accepts a "related" btest connection before the corresponding primary session has completed authentication. An unauthenticated client can use this state to start an IPv4 UDP test. With "random-data=false", the sender transmits an uninitialized tail from a kernel packet buffer. A separate...
