How to fix?

Upgrade Debian:11 glibc to version 2.2-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream glibc package and not the glibc package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

manual/search.texi in the GNU C Library (aka glibc) before 2.2 lacks a statement about the unspecified tdelete return value upon deletion of a tree's root, which might allow attackers to access a dangling pointer in an application whose developer was unaware of a documentation update from 1999.
