CVE-2024-45615: Libopensc: pkcs15init: usage of uninitialized values in libopensc and pkcs15init
A vulnerability was found in OpenSC, OpenSC tools, PKCS#11 module, minidriver, and CTK.
The problem is missing initialization of variables expected to be initialized (as arguments to other functions, etc.).
Security readout for executives and security teams
Plain-English summary
CVE-2024-45615 is a low-severity OpenSC issue involving values that may be used before proper initialization. Business risk is limited by required physical access and high attack complexity, but organizations using smart-card authentication on affected Linux systems should still track vendor updates.
Executive priority
Treat as routine patch management unless the organization relies heavily on smart-card authentication. The issue has low severity, no KEV signal, and physical-access constraints, but affected identity infrastructure should remain current.
Technical view
The bundle describes missing initialization in OpenSC, including libopensc, tools, PKCS#11 module, minidriver, CTK, and pkcs15init. It is classified as CWE-457 with CVSS 3.1 score 3.9, AV:P/AC:H, and low confidentiality, integrity, and availability impact.
Likely exposure
Exposure is most likely on systems with OpenSC/opensc installed for smart-card or PKCS#11 workflows. The bundle lists Red Hat Enterprise Linux 7, 8, 9, and 10 opensc as affected. Exact upstream version boundaries are not provided.
Exploitation context
The source bundle does not show CISA KEV listing or cited evidence of active exploitation. The CVSS vector requires physical access and high attack complexity, which limits broad remote exploitation risk.
Researcher notes
Evidence is limited to the provided CVE metadata and referenced vendor sources. The affected-version detail is incomplete beyond listed RHEL products and package name opensc. Do not assume broader product impact without vendor confirmation.
Mitigation direction
Inventory OpenSC or opensc installations on Linux endpoints and servers.
Prioritize systems using smart-card authentication or PKCS#11 integrations.
Apply Red Hat or Debian vendor updates when provided for your platform.
Monitor the Red Hat CVE page and Debian advisory for package-specific remediation.
If no update is available, follow vendor guidance for compensating controls.
Validation and detection
Check installed OpenSC or opensc package versions against vendor advisories.
Confirm whether affected systems use smart cards, PKCS#11, minidriver, or CTK components.
Review Red Hat advisories for RHEL 7, 8, 9, and 10 applicability.
Verify patch deployment through endpoint or package management reporting.

Use the exact CWE identifier as the starting point before reviewing related ATT&CK behavior. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.
We collect every scored CVSS vector available in the official CNA and ADP containers. When more than one version is present, the table keeps the source vectors side by side instead of collapsing them into the highest score.

Use of Uninitialized Variable
Use of Uninitialized Variable represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
