CVE-2025-23395 is a high-severity Privilege Dropping / Lowering Errors (CWE-271) vulnerability in Suse (inferred from references). Its CVSS base score is 7.3 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Setuid and Setgid (T1548.001); ranked at the 10th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to AC-6 (Least Privilege) and AC-3 (Access Enforcement) — see the control section below for these in your framework.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
Least privilege explicitly mandates dropping privileges to the minimum necessary before transferring control.
Access enforcement directly requires that privileges are lowered before handing resources to less-privileged actors.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Explicit inclusion of least-privilege policy directly addresses failure to drop privileges before handing control to lower-privileged actors.
Secure-development practices encompass correct privilege-dropping logic, though the control is broader than this single weakness.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Restricting use of privileged utility programs forces explicit privilege lowering before handing control to unprivileged actors.
Privileged access rights explicitly require least-privilege assignment and timely revocation, directly mitigating failure to drop privileges.
Secure development lifecycle includes privilege management reviews, providing indirect coverage of the weakness.
Secure coding standards can mandate privilege-dropping calls, yet the control is broader than this single weakness.
Information access restriction policies can limit privilege scope but do not specifically address dropping privileges at runtime.
