A vulnerability identified as CVE-2023-28938 was discovered in Intel(R) SSD Tools software, specifically affecting mdadm versions before 4.2-rc2. The vulnerability was disclosed on August 8, 2023, and involves uncontrolled resource consumption that could lead to potential security issues (Intel Advisory, NVD).

The vulnerability is classified as CWE-400 (Uncontrolled Resource Consumption) and has received varying CVSS scores. The National Institute of Standards and Technology (NIST) assigned a CVSS v3.1 base score of 4.4 (Medium) with a vector of CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H, while Intel Corporation rated it at 3.4 (Low) with a vector of CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:L/I:N/A:L (NVD).
