Created kernel tracking bugs for this issue: Affects: fedora-all [bug 2273235] The result of automatic check (that is developed by Alexander Larkin) for this CVE-2024-26774 is: CHECK Maybe valid. Check manually. with impact LOW (that is approximation based on flags DISK INIT SIMPLEFIX ; 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 Via RHSA-2024:9315 https://access.redhat.com/errata/RHSA-2024:9315 |
