Upgrade Debian:11 glibc to version 2.31-5 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.
The iconv function in the GNU C Library (aka glibc or libc6) 2.32 and earlier, when processing invalid multi-byte input sequences in IBM1364, IBM1371, IBM1388, IBM1390, and IBM1399 encodings, fails to advance the input state, which could lead to an infinite loop in applications, resulting in a denial of service, a different vulnerability from CVE-2016-10228.
