The Debian security team deemed this advisory irrelevant for Debian:10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream tomcat9 package and not the tomcat9 package as distributed by Debian.
The fix for bug 63362 present in Apache Tomcat 10.1.0-M1 to 10.1.0-M5, 10.0.0-M1 to 10.0.11, 9.0.40 to 9.0.53 and 8.5.60 to 8.5.71 introduced a memory leak. The object introduced to collect metrics for HTTP upgrade connections was not released for WebSocket connections once the connection was closed. This created a memory leak that, over time, could lead to a denial of service via an OutOfMemoryError.
