Incomplete Patch

A security fix that blocks the reported exploit path without correcting the underlying weakness, leaving an alternative route to the same bug. The follow-up is often assigned its own CVE; N-central's CVE-2026-18577 was formally described as the result of an incomplete patch for CVE-2026-18556.
