Description ybuenos 2024-05-23 10:15:10 UTC 
In the Linux kernel, the following vulnerability has been resolved:

nvmem: Fix shift-out-of-bound (UBSAN) with byte size cells

The Linux kernel CVE team has assigned CVE-2021-47497 to this issue.

Upstream advisory:
https://lore.kernel.org/linux-cve-announce/2024052242-CVE-2021-47497-449e@gregkh/T
Comment 4 Alex 2024-06-09 17:09:06 UTC 
The result of automatic check (that is developed by Alexander Larkin) for this CVE-2021-47497 is: CHECK	Maybe valid. Check manually. with impact LOW (that is an approximation based on flags WRITE KASAN OOB NVME  ; 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.
