Summary

CVE-2024-58262 is a low-severity Compiler Optimization Removal or Modification of Security-critical Code (CWE-733) vulnerability in Dalek Curve25519-Dalek. Its CVSS base score is 2.9 (Low).

Operationally, exploitation aligns with the MITRE ATT&CK technique OS Credential Dumping (T1003); 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 SA-11 (Developer Testing and Evaluation) and SA-15 (Development Process, Standards, and Tools) — see the control section below for these in your framework.

SA-11 Developer Testing and Evaluation partial match

Developer testing and evaluation can reveal cases where security code has been optimized away.

SA-15 Development Process, Standards, and Tools partial match

Documented developer processes and standards can mandate coding patterns and compiler flags that preserve security-critical operations.

SA-8 Security and Privacy Engineering Principles partial match

Security engineering principles include requirements for correct implementation of protection mechanisms that survive compilation.
