How to fix?

Upgrade SLES:15.0 tomcat-jsp-2_3-api to version 9.0.36-3.84.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream tomcat-jsp-2_3-api package and not the tomcat-jsp-2_3-api package as distributed by SLES:15.0. See How to fix? for SLES:15.0 relevant fixed versions and status.

Apache Tomcat 8.5.0 to 8.5.63, 9.0.0-M1 to 9.0.43 and 10.0.0-M1 to 10.0.2 did not properly validate incoming TLS packets. When Tomcat was configured to use NIO+OpenSSL or NIO2+OpenSSL for TLS, a specially crafted packet could be used to trigger an infinite loop resulting in a denial of service.
