This issue has been addressed in the following products: Red Hat Enterprise Linux 9 Via RHSA-2024:2394 https://access.redhat.com/errata/RHSA-2024:2394 This issue has been addressed in the following products: Red Hat Enterprise Linux 8 Via RHSA-2024:2950 https://access.redhat.com/errata/RHSA-2024:2950 This issue has been addressed in the following products: Red Hat Enterprise Linux 8 Via RHSA-2024:3138 https://access.redhat.com/errata/RHSA-2024:3138 The result of automatic check (that is developed by Alexander Larkin) for this CVE-2023-52448 is: CHECK Maybe valid. Check manually. with impact MODERATE (that is approximation based on flags NULLPTR DISK SIMPLEFIX IMPROVEONLY ; these flags parsed automatically based on patche data). Such automatic check happens only for Low/Moderates (and only when not from reporter, but parsing already existing CVE). Highs always checked manually (I check it myself and then we check it again in Remediation team). In rare cases some of the Moderates could be increased to High later.
