The vulnerability was revealed publicly in June by Trend Micro's Zero Day Initiative (ZDI) following six months spent chivvying Netgear behind the scenes to take it seriously.
Keen-eyed Reg readers, however, noticed that Netgear quietly declared 45 of the affected products as "outside the security support period" – meaning those items won't be updated to protect them against the vulnerability.

That's one way of speeding up the tech refresh cycle
