How to fix?

Upgrade SLES:15.2 kernel-default-base to version 5.3.18-150200.24.134.1.150200.9.63.2 or higher.

NVD Description

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

The Linux kernel before 5.17.9 allows TCP servers to identify clients by observing what source ports are used. This occurs because of use of Algorithm 4 ("Double-Hash Port Selection Algorithm") of RFC 6056.
