How to fix?

Upgrade SLES:15.1 kubernetes-common to version 1.17.13-4.21.2 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kubernetes-common package and not the kubernetes-common package as distributed by SLES. See How to fix? for SLES:15.1 relevant fixed versions and status.

In etcd before versions 3.3.23 and 3.4.10, a large slice causes panic in decodeRecord method. The size of a record is stored in the length field of a WAL file and no additional validation is done on this data. Therefore, it is possible to forge an extremely large frame size that can unintentionally panic at the expense of any RAFT participant trying to decode the WAL.
