Description Robb Gatica 2024-04-03 23:17:51 UTC 
In the Linux kernel, the following vulnerability has been resolved:

mm/writeback: fix possible divide-by-zero in wb_dirty_limits(), again

The Linux kernel CVE team has assigned CVE-2024-26720 to this issue.

Upstream advisory:
https://lore.kernel.org/linux-cve-announce/2024040344-CVE-2024-26720-06fa@gregkh/T
Comment 1 Robb Gatica 2024-04-03 23:18:31 UTC 
Created kernel tracking bugs for this issue:

Affects: fedora-all [bug 2273142]
Comment 3 Alex 2024-06-09 15:03:18 UTC 
The result of automatic check (that is developed by Alexander Larkin) for this CVE-2024-26720 is: CHECK	Maybe valid. Check manually. with impact MODERATE (that is approximation based on flags DEADLOCK 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.
