How to fix?

There is no fixed version for Ubuntu:22.04 cups.

NVD Description

Note: Versions mentioned in the description apply only to the upstream cups package and not the cups package as distributed by Ubuntu. See How to fix? for Ubuntu:22.04 relevant fixed versions and status.

The cupsUTF32ToUTF8() function in CUPS's cups/transcode.c lacks a source-length bound and can read past the end of the source buffer, resulting in a heap out-of-bounds read. This is reachable via SNMP supply-description parsing in backend/snmp-supplies.c with attacker-controlled content.
