NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-livepatch-5_3_18-24_67-default package and not the kernel-livepatch-5_3_18-24_67-default package as distributed by SLES.
See How to fix? for SLES:15.2 relevant fixed versions and status.
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.
