CVE-2026-74494

A flaw was found in ksmbd, a kernel module for SMB3 protocol support. An unauthenticated client can send multiple SMB2 NEGOTIATE requests on a single connection before a session is established. This leads to a memory leak, as previous allocations are not properly freed. Repeated exploitation of...
