The Linux kernel CVE team has assigned CVE-2024-26973 to this issue.

Upstream advisory: https://lore.kernel.org/linux-cve-announce/2024050132-CVE-2024-26973-54a3@gregkh/T

This vulnerability is rated as Low severity because it only allows a local user to obtain two bytes of uninitialized kernel memory, posing a minimal risk to confidentiality with no impact on system integrity or availability. The flaw requires interaction with a FAT filesystem utilizing nostale file handle encoding, which is an uncommon configuration and not standard across default Red Hat Enterprise Linux installations. Consequently, the potential for practical exploitation or exposure of sensitive data remains extremely limited under typical operational environments.
