Issue Overview: Perl versions through 5.43.9 produce silently incorrect regular expression matches when an alternation of more than 65535 fixed string branches is compiled into a trie in Perlstudychunk. When such branches are combined into a trie, the delta between the first branch and the shared...

CVE-2026-57432

A flaw was found in Perl. An integer overflow vulnerability in the Smeasurestruct function, specifically when handling pack and unpack templates with large repeat counts, can lead to an out-of-bounds heap read. This allows an attacker, by providing a specially crafted template, to read sensitive...
