CVE-2026-67277 Kernel memory disclosure and denial of service in MikroTik RouterOS btest service

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...

CVE-2026-67277

MikroTik RouterOS btest service is vulnerable to unauthenticated kernel memory disclosure and denial of service . An unauthenticated attacker can exploit a race condition where a "related" btest connection is accepted before primary session authentication completes, then start an IPv4 UDP test. W...
