How we built this timeline

Kept separate from CVE-2025-23006 (sonicwall-cve-2025-23006): different advisory and a different time; SonicWall says the only known exploitation paths require CVE-2025-23006 to be unpatched (fixed since 22 Jan 2025) or prior local access. exploited before a fix is set true because exploitation was acknowledged in the same advisory that first published the fix; if the fixed builds shipped earlier than 17 Dec 2025 (not verified), that could change.

Revision history: v1.0 17-Dec-2025 initial release; v1.1 18-Dec-2025 risk assessment note added. Severity: SonicWall CVSS 6.6 (medium).

The human-readable advisory page is a JavaScript app; the PSIRT JSON API record is cited. R7 (23 Oct 2026): CVE-2025-40602 was exploited in a chain with CVE-2025-23006, but the two were disclosed eleven months apart (22 Jan 2025 and 17 Dec 2025), so they stay separate incidents (cross-reference: sonicwall-cve-2025-23006 / sonicwall-cve-2025-40602).

T1 check (23 Oct 2026): SMA1000 release notes (sonicwall.com technical documentation) are JavaScript-only, so the release date of 12.4.3-03245 / 12.5.0-02283 could not be checked; First fix stays an upper bound and exploited before a fix stays true on the advisory evidence.
