There is no fixed version for Ubuntu:20.04 php7.4.

NVD Description

Note: Versions mentioned in the description apply only to the upstream php7.4 package and not the php7.4 package as distributed by Ubuntu. See How to fix? for Ubuntu:20.04 relevant fixed versions and status.

PHP through 5.6.27 and 7.x through 7.0.12 mishandles property modification during __wakeup processing, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via crafted serialized data, as demonstrated by Exception::__toString with DateInterval::__wakeup.
