CVE-2026-12549[0]: | The fix for CVE-2026-2443 was regressed by a subsequent rework | commit that replaced specific overflow checks with a general signed | comparison. When a client sends a Range request with a suffix length | exceeding the content size, the resulting negative start value is | not properly clamped, leading to malformed HTTP 206 responses and | log flooding. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
