How to fix?

Upgrade SLES:15.3 postgresql12-server to version 12.17-150200.8.54.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream postgresql12-server package and not the postgresql12-server package as distributed by SLES. See How to fix? for SLES:15.3 relevant fixed versions and status.

A flaw was found in PostgreSQL involving the pg_cancel_backend role that signals background workers, including the logical replication launcher, autovacuum workers, and the autovacuum launcher. Successful exploitation requires a non-core extension with a less-resilient background worker and would affect that specific background worker only. This issue may allow a remote high privileged user to launch a denial of service (DoS) attack.
