| Doc Text: |
A race condition was found on a PFN in the Linux Kernel, which can fall into the device memory region with the system memory configuration. Normal zone start and end PFNs contain the device memory PFNs as well, and the compaction triggered will try on the device memory PFNs and end up in NOP. This may lead to compromised Availability.

Created kernel tracking bugs for this issue: Affects: fedora-all [bug 2269190] This was fixed for Fedora with the 6.7.3 stable kernel updates. 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-2023-52489 is: CHECK Maybe valid. Check manually. with impact MODERATE (that is approximation based on flags READ LOCK DANGER NULLPTR RACE ; 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. This issue has been addressed in the following products: Red Hat Enterprise Linux 9.0 Update Services for SAP Solutions Via RHSA-2024:6990 https://access.redhat.com/errata/RHSA-2024:6990 This issue has been addressed in the following products: Red Hat Enterprise Linux 9.0 Update Services for SAP Solutions Via RHSA-2024:6991 https://access.redhat.com/errata/RHSA-2024:6991 |
