Deeper analysis
CVE-2025-24072 is a use-after-free vulnerability (CWE-416) in the Microsoft Local Security Authority Server (lsasrv) component. It affects Microsoft Windows operating systems and was published on 2025-03-11 with a CVSS v3.1 base score of 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to its potential for significant impact.
An authorized local attacker with low privileges (PR:L) can exploit this vulnerability through a low-complexity attack (AC:L) with no user interaction required (UI:N). Successful exploitation enables local privilege escalation, granting high impacts on confidentiality, integrity, and availability (C:H/I:H/A:H) within the unchanged security scope (S:U).
The Microsoft Security Response Center (MSRC) provides details on this vulnerability, including patch information and mitigation guidance, in their Update Guide at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2025-24072.
