CVE-2026-40528 (GCVE-0-2026-40528)

Vulnerability from cvelistv5 – Published: 2026-05-29 13:38 – Updated: 2026-05-29 13:58 X_Open Source

Title

OpenSC < 0.27.0 Buffer Overrun in do_key_value() via profile.c

Summary

OpenSC before 0.27.0, fixed in commit 0358817, contains a stack and heap buffer overrun vulnerability in the do_key_value() function in src/pkcs15init/profile.c that allows attackers to corrupt memory by supplying a crafted profile configuration file. During pkcs15-init invocation, a key value entry beginning with '=' followed by more than sizeof(keybuf) characters is copied into keybuf via memcpy without a length check, causing both stack and heap buffer overruns.
