CVE-2026-13221

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 tail is stored ...

CVE-2026-13221

CVE-2026-13221 affects Perl versions through 5.43.9. When an alternation of more than 65,535 fixed-string branches is compiled into a trie in Perl_study_chunk, the 16‑bit delta between the first branch and the shared tail overflows. The trie’s match decision table is truncated with no warning, pr...

CVE-2026-56015

CVE-2026-56015 affects Net::IP::LPM v1.10 and earlier for Perl, enabling a heap out-of-bounds read when adding prefixes with unbounded lengths. The bug arises in addPrefixToTrie() which walks the prefix buffer by prefix_length bits without verifying it against the address width (4 bytes IPv4, 16 ...

PT-2026-55535

Name of the Vulnerable Software and Affected Versions Net::IP::LPM versions prior to 1.11 Description An issue exists where a heap out-of-bounds read can occur due to an unbounded prefix length.

CVE-2026-55892

Vim is an open source, command line text editor. Prior to 9.2.0662, the dumpprefixes function in src/spell.c walks a spell-file prefix trie iteratively with a depth counter while dumping the prefixes that apply to a word. The counter is bounded only by the trie structure itself; it is never check...

CVE-2026-55693 Vim: Out-of-bounds Write in Spell File Word Count

Vim is an open source, command line text editor. Prior to 9.2.0653, the treecountwords function in src/spellfile.c fills in the word-count fields of a spell-file word trie by walking it iteratively with a depth counter. The counter is bounded only by the trie structure itself; it is never checked...
