CVE-2026-109243
Description
A flaw was found in FreeRDP. When software-based smartcard authentication is used on multi-user systems, FreeRDP writes a temporary copy of the private key to a shared directory without enforcing owner-only file permissions. A local, unprivileged attacker can access this shared directory and read the world-readable file, leading to the disclosure of sensitive cryptographic credentials.
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.
