Raw vector
CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:NSummary
CVE-2024-46975 is a high-severity Privilege Context Switching Error (CWE-270) vulnerability in Imaginationtech (inferred from references). Its CVSS base score is 7.9 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Access Token Manipulation (T1134); ranked at the 5th 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-3 (Access Enforcement) and AC-6 (Least Privilege) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2024-46975 is a vulnerability affecting GPU firmware and drivers, specifically those from Imagination Technologies, in virtualized environments. Kernel software running inside a Guest VM can exploit memory shared with the GPU Firmware to arbitrarily write data into another Guest's virtualized GPU memory. This issue, associated with CWE-270 (Permissions, Privileges, and Access Controls), carries a CVSS v3.1 base score of 7.9 (AV:L/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:N), indicating high severity due to its potential for cross-VM impact.
A local attacker with low privileges in a compromised Guest VM can exploit this vulnerability, requiring low complexity and user interaction. Successful exploitation allows writing to another Guest's virtualized GPU memory, achieving high confidentiality and integrity impacts with a changed scope, enabling data corruption or exfiltration across VM isolation boundaries in multi-tenant setups.
Mitigation details are provided in the vendor advisory at https://www.imaginationtech.com/gpu-driver-vulnerabilities/, which likely includes patches or configuration guidance for affected GPU drivers and firmware in virtualized deployments.

Mitigating Controls (NIST 800-53 r5) AI
AC-3 enforces access authorizations according to policy at every request, structurally preventing incorrect privilege elevation or retention across context switches.
AC-6 requires least-privilege assignments and privilege minimization, reducing the opportunity for erroneous privilege state during context transitions.
AC-24 mandates that access-control decisions be made and enforced correctly for each request, directly addressing flawed privilege context switches.

Enforcing least-privilege authorization policies and reviews directly prevents improper privilege changes across contexts.
Integrating secure-development practices catches and eliminates context-switching privilege errors during design and coding.

Privileged-access-rights control directly addresses improper privilege elevation during context switches.
Access-control policy defines privilege boundaries but does not guarantee correct switching logic.
Managing access rights includes privilege assignment but not runtime context-switch enforcement.
Restricting privileged utilities reduces exposure to context-switch privilege errors.
Secure-SDLC practices can catch privilege-handling defects early but do not guarantee runtime correctness.
Secure-architecture principles encourage least-privilege context separation but leave implementation details open.
