Mitigating Controls
Control response
Mitigating Controls (NIST 800-53 r5) AI
Directly implements hardware/software memory protection mechanisms to block unauthorized write permission bypasses in kernel modules such as futex.
Enforces access control decisions on memory objects so that a futex permission bypass cannot result in unauthorized writes.
Restricts privileges granted to processes and kernel components, limiting the impact and exploitability of a futex memory-write bypass.
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.
Defining, enforcing and reviewing access permissions with least privilege directly prevents code paths that mishandle insufficient privileges.
Runtime monitoring of software and data surfaces adverse events triggered by unhandled permission failures.
Generating logs of permission-related events enables detection and analysis of improper handling.
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.
Security testing can detect missing or incorrect privilege handling.
Defines access-control policy that should prevent insufficient-privilege situations.
Specifies how access rights are granted, reviewed and revoked, directly addressing privilege handling.
Requires explicit management of privileged access rights, reducing the chance of missing privilege checks.
Secure-SDLC practices include privilege checks during design and coding.
Secure-coding standards require proper permission checks before resource access.
