Oracle Linux: CVE-2020-24586: ELSA-2021-9406: Unbreakable Enterprise kernel-container security update (IMPORTANT) (Multiple Advisories)
Description
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. A flaw was found in the Linux kernels implementation of wifi fragmentation handling. An attacker with the ability to transmit within the wireless transmission range of an access point can abuse a flaw where previous contents of wifi fragments can be unintentionally transmitted to another device.
