Created kernel tracking bugs for this issue: Affects: fedora-all [bug 2269184] This was fixed for Fedora with the 6.7.3 stable kernel updates. The result of automatic check (that is developed by Alexander Larkin) for this CVE-2023-52492 is: CHECK Maybe valid. Check manually. with impact LOW (that is an approximation based on flags NULLPTR INIT ERRORPATH DMAorINTERRUPT HARDWARE ; these flags parsed automatically based on patch 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. This issue has been addressed in the following products: Red Hat Enterprise Linux 8 Via RHSA-2024:8870 https://access.redhat.com/errata/RHSA-2024:8870 This issue has been addressed in the following products: Red Hat Enterprise Linux 8 Via RHSA-2024:8856 https://access.redhat.com/errata/RHSA-2024:8856 This issue has been addressed in the following products: Red Hat Enterprise Linux 9 Via RHSA-2024:9315 https://access.redhat.com/errata/RHSA-2024:9315 This issue has been addressed in the following products: Red Hat Enterprise Linux 9.4 Extended Update Support Via RHSA-2025:7526 https://access.redhat.com/errata/RHSA-2025:7526 |
