CVE-2024-45616

Data exposure and corruption via unchecked APDU lengths

Published Sep 3, 2024 · Updated Jun 30, 2026

Use of uninitialized memory in OpenSC before 0.26.0 allows physically proximate attackers to disclose or alter data or interrupt service. Multiple libopensc card-driver paths trust response lengths or status bytes and then read uninitialized portions of APDU buffers. A crafted USB device or smart card must supply malformed APDU responses; the reported effects are limited to low-impact disclosure, alteration, or interruption.
