The most recent Sma 500v flaw added to the known-exploited list is CVE-2023-44221, on 1 May 2025. We keep watching the known-exploited list.
Is Sma 500v listed under other names? Yes.
SonicWall also lists Sma 500v under more specific names, such as Sma 500v Firmware. Flaws listed only under those names are counted on their own pages, not here. If you run one of these, open its page for its own exploited flaws.
Which versions of Sma 500v do the exploited flaws hit?
Each exploited flaw lists the versions it affects, usually as ranges. "before 9.0.0.11-31sv" means every version up to, but not including, 9.0.0.11-31sv. Find your version, then patch.
