CVE-2024-58262
Description
A flaw was found in curve25519-dalek. The crate’s implementation of constant-time operations on elliptic curve scalars lacks proper LLVM optimization, potentially revealing information about the scalar's bits. A local attacker can observe timing differences during scalar operations. This information leak occurs via direct execution of the vulnerable code. The consequence is a potential side-channel attack.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
