How to fix?

Upgrade SLES:15.3 php7-sysvmsg to version 7.4.33-150200.3.46.2 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream php7-sysvmsg package and not the php7-sysvmsg package as distributed by SLES. See How to fix? for SLES:15.3 relevant fixed versions and status.

In PHP versions 7.2.x below 7.2.34, 7.3.x below 7.3.23 and 7.4.x below 7.4.11, when AES-CCM mode is used with openssl_encrypt() function with 12 bytes IV, only first 7 bytes of the IV is actually used. This can lead to both decreased security and incorrect encryption data.
