CVE-2026-93433 — MEDIUM (5.5)

Vulnerability Description

A flaw was found in libstoragemgmt. An attacker with control over a local or virtual storage device could provide specially crafted SCSI (Small Computer System Interface) Vital Product Data (VPD) page 0x80 data.

Successful exploitation could result in a denial of service by crashing or destabilizing the process querying the serial number.
