Comment 1 Mauro Matteo Cascella 2024-04-02 23:49:48 UTC

Created kernel tracking bugs for this issue:

Affects: fedora-all [bug 2272825]

Comment 5 Justin M. Forbes 2024-04-03 16:34:37 UTC

This was fixed for Fedora with the 6.7.5 stable kernel updates.

Comment 12 Alex 2024-06-09 15:48:30 UTC

The result of automatic check (that is developed by Alexander Larkin) for this CVE-2024-26684 is: CHECK	Maybe valid. Check manually. with impact LOW (that is approximation based on flags REMOTE NETWORK DMAorINTERRUPT 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.
