CVE-2026-73584 is an insecure temporary-file handling race condition in sblim-sfcb during privileged instance migration. A local low-privileged attacker can repeatedly replace a temporary file with a symbolic link between file-handling operations, causing privileged output to be redirected to an attacker-selected file. The flaw can result in privileged file corruption or denial of service.
