NVD Description
Note: Versions mentioned in the description apply only to the upstream php-devel package and not the php-devel package as distributed by Centos.
See How to fix? for Centos:8 relevant fixed versions and status.
In PHP versions 7.2.x below 7.2.28, 7.3.x below 7.3.15 and 7.4.x below 7.4.3, when using file upload functionality, if upload progress tracking is enabled, but session.upload_progress.cleanup is set to 0 (disabled), and the file upload fails, the upload procedure would try to clean up data that does not exist and encounter null pointer dereference, which would likely lead to a crash.
