How to fix?

There is no fixed version for Ubuntu:22.04 xz-utils.

NVD Description

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

An issue discovered in XZ 5.2.5 allows attackers to cause a denial of service via decompression of a crafted file. NOTE: the vendor disputes the claims of "endless output" and "denial of service" because decompression of the 17,486 bytes always results in 114,881,179 bytes, which is often a reasonable size increase.
