CVE-2026-40528
Description
A flaw was found in OpenSC. A local attacker can exploit this vulnerability by supplying a specially crafted profile configuration file to the pkcs15-init utility. This can lead to a stack and heap buffer overrun, allowing the attacker to corrupt memory. This memory corruption could potentially result in a denial of service or other unpredictable system behavior.
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.
