CVE-2025-6573 is a critical vulnerability (CVSS 9.8, CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) published on 2025-08-09, affecting kernel software installed and running inside an untrusted or rich execution environment (REE). The flaw, classified under CWE-280 (improper handling of insufficient privileges or access), enables this kernel software to leak sensitive information from the trusted execution environment (TEE). It impacts Imagination Technologies GPU drivers, as detailed in their vulnerability advisory.
Remote, unauthenticated attackers can exploit this vulnerability over the network with low complexity and no user interaction required. Successful exploitation allows high-impact compromise of confidentiality by leaking TEE data, alongside high integrity and availability impacts, potentially enabling data theft, modification, or denial of service within the affected environments.

Mitigating Controls (NIST 800-53 r5) AI
Ensuring access decisions are applied to every request structurally prevents the product from taking unexpected paths when privileges are lacking.
A reference monitor that is always invoked guarantees privilege checks occur, eliminating the root condition for improper insufficient-privilege handling.
Access enforcement directly stops code from proceeding on insufficient privileges by applying authorization checks before resource access.
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.
