Doc Text:
A vulnerability was found in the pstore/ram component of the Linux kernel, which caused crashes when the number of CPU cores was set to an odd number. This issue occurs because the odd-numbered zones became misaligned. This flaw allows a local, authenticated attacker to cause a denial of service.

Description Zack Miele 2024-03-18 13:11:01 UTC 
In the Linux kernel, the following vulnerability has been resolved:

pstore/ram: Fix crash when setting number of cpus to an odd number

The Linux kernel CVE team has assigned CVE-2023-52619 to this issue.

Upstream advisory:
https://lore.kernel.org/linux-cve-announce/20240318102117.2839904-9-lee@kernel.org/T
Comment 1 Zack Miele 2024-03-18 13:11:34 UTC 
Created kernel tracking bugs for this issue:

Affects: fedora-all [bug 2270085]
Comment 5 Justin M. Forbes 2024-03-26 16:07:00 UTC 
This was fixed for Fedora with the 6.7.4 stable kernel updates.
Comment 8 Alex 2024-06-09 15:12:25 UTC 
The result of automatic check (that is developed by Alexander Larkin) for this CVE-2023-52619 is: CHECK	Maybe valid. Check manually. with impact MODERATE (that is approximation based on flags DANGER 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.
