CVE-2026-9265 is a critical-severity vulnerability rated 9.1/10 on the CVSS scale. Crypt::OpenSSL::PKCS12 versions before 1.96 for Perl permits a heap OOB read in print_attribute UTF8STRING path. print_attribute() copies a UTF8STRING ASN.1 attribute value into a heap buffer sized exactly to its declared length via strncpy, leaving no NUL terminator. Downstream callers run strlen() on the result and pass the inflated length to newSVpvn(), copying attacker-influenced adjacent heap bytes into a Perl scalar.. EPSS estimates a 0.35% chance of exploitation in the next 30 days.
