Newly discovered Wi-Fi security vulnerabilities collectively known as FragAttacks (fragmentation and aggregation attacks) are impacting all Wi-fi devices (including computers, smartphones, and smart devices) going back as far as 1997. Three of these bugs are Wi-FI 802.11 standard design flaws in the frame aggregation and frame fragmentation functionalities affecting most devices. Some programming mistakes behind some of the vulnerabilities are trivial to exploit and would allow attackers to abuse unpatched products with ease. Security updates already released by some vendors are developing patches for their product to mitigate the bugs.
