CVE-2024-45618: Libopensc: uninitialized values after incorrect or missing checking return values of functions in pkcs15init

LowCVSS 3.9 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 15/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.31% (FIRST EPSS).
  • Physical access to the device is required. No account or password is required. No user action is required. Special conditions such as timing or configuration are required.
  • Fixed version: opensc (Alpine:v3.21) 0.26.0-r0; opensc (Debian:11) 0.21.0-1+deb11u1; opensc (Debian:12) 0.23.0-0.3+deb12u2.

Low priority for now. Upgrade to opensc (Alpine:v3.21) 0.26.0-r0; opensc (Debian:11) 0.21.0-1+deb11u1; opensc (Debian:12) 0.23.0-0.3+deb12u2 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

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.
