Description ybuenos 2024-05-22 08:55:40 UTC 
In the Linux kernel, the following vulnerability has been resolved:

hwmon: (mlxreg-fan) Return non-zero value when fan current state is enforced from sysfs

The Linux kernel CVE team has assigned CVE-2021-47393 to this issue.

Upstream advisory:
https://lore.kernel.org/linux-cve-announce/2024052147-CVE-2021-47393-ea1c@gregkh/T
Comment 4 Alex 2024-06-09 16:10:02 UTC 
The result of automatic check (that is developed by Alexander Larkin) for this CVE-2021-47393 is: CHECK	Maybe valid. Check manually. with impact MODERATE (that is an approximation based on flags READ KASAN OOB  ; these flags parsed automatically based on patch 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.
