CVE-2024-45618: Use of Uninitialized Variable
A vulnerability was found in pkcs15-init in OpenSC. An attacker could use a crafted USB Device or Smart Card, which would present the system with a specially crafted response to APDUs. Insufficient or missing checking of return values of functions leads to unexpected work with variables that have not been initialized.
AI Analysis
Technical Summary
This vulnerability in OpenSC's pkcs15-init occurs due to improper handling of function return values, resulting in operations on uninitialized variables. An attacker controlling a USB device or smart card can send crafted APDU responses that trigger this condition. The issue could lead to limited impacts on confidentiality, integrity, and availability as indicated by the CVSS vector (AV:P/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L). No known exploits are reported in the wild.
Potential Impact
The vulnerability may allow an attacker with physical access to a USB device or smart card interface to cause unexpected behavior due to uninitialized variables. The CVSS score of 3.9 reflects low impact, with potential limited confidentiality, integrity, and availability effects. There is no indication of remote exploitation without physical access or elevated privileges.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory at https://access.redhat.com/security/cve/CVE-2024-45618 for current remediation guidance. No official fix or patch links are provided in the available data. Until a patch is available, limit exposure to untrusted USB devices or smart cards to reduce risk.
