Summary

CVE-2024-7883 is a low-severity Sensitive Information in Resource Not Removed Before Reuse (CWE-226) vulnerability in Arm Arm Compiler For Embedded Fusa. Its CVSS base score is 3.7 (Low).

Operationally, exploitation aligns with the MITRE ATT&CK technique OS Credential Dumping (T1003); ranked at the 38th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to MP-6 (Media Sanitization) and SC-4 (Information in Shared System Resources) — see the control section below for these in your framework.

Vulnerability Data

When using Arm Cortex-M Security Extensions (CMSE), Secure stack contents can be leaked to Non-secure state via floating-point registers when a Secure to Non-secure function call is made that returns a floating-point value and when this is the first use…

of floating-point since entering Secure state. This allows an attacker to read a limited quantity of Secure stack contents with an impact on confidentiality. This issue is specific to code generated using LLVM-based compilers.

Mitigating Controls (NIST 800-53 r5) AI

MP-6 Media Sanitization good match

MP-6 requires sanitization of media before release for reuse, directly stopping sensitive data from remaining in resources made available to others.

SC-4 Information in Shared System Resources good match

SC-4 requires preventing unintended information transfer through shared system resources such as memory, which is achieved by clearing data before reuse.

PR.DS-10 full match
prevents

Explicit example calls for removing confidential data (e.g., from process memory) after use, directly preventing reuse of uncleared resources.

A.8.10 Information deletion full match
degrades

Explicitly requires secure deletion of information before resources are reused or disposed.

A.7.14 Secure disposal or re-use of equipment mostly match
prevents

Mandates secure disposal or re-use of equipment, covering media sanitization but not in-memory reuse.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing can detect failures to sanitize resources before reuse.

A.8.25 Secure development life cycle partial match
prevents

Secure SDLC includes requirements for clearing sensitive data during resource lifecycle transitions.

A.8.28 Secure coding partial match
prevents

Secure coding practices can prevent leaving sensitive data in memory or files before reuse.
