CVSS 3.1
3.5 lowCVSS:3.1/AV:A/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:NCVE-2020-24586
Low (3.5). EPSS 5.8% chance of exploitation in the next 30 days.
The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that received fragments be cleared from memory after (re)connecting to a network. Under the right circumstances, when another device sends fragmented frames encrypted using WEP, CCMP, or GCMP, this can be abused to inject arbitrary network packets and/or exfiltrate user data.
