CVE-2026-40510

Estado: AnalizadaBaja (1)—

OpenSC before 0.27.0-rc1, fixed in commit 3f24f0b, contains a stack buffer overflow vulnerability in piv_process_history() in src/libopensc/card-piv.c that allows physically present attackers to trigger memory corruption by presenting a crafted PIV smart card or USB device returning a URL field longer than 118 bytes in the Key History Object ASN.1 response.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
