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 all fragments of a frame are encrypted under the same key. An adversary can abuse this to decrypt selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP encryption key is periodically renewed.
