CVE-2026-8376 (opens in a new tab)Amendment
The Minimos security team deemed this advisory irrelevant for Minimos:latest.
NVD Description
Note: Versions mentioned in the description apply only to the upstream perl-5.38-utils package and not the perl-5.38-utils package as distributed by Minimos.
Perl versions before 5.40.5-RC1, from 5.41.0 before 5.42.3-RC1, from 5.43.0 before 5.43.11 have a heap buffer overflow when compiling regular expressions with a repeated fixed string on 32-bit builds.
Perl_study_chunk in regcomp_study.c checked the size of the joined substring buffer in characters rather than bytes. For a quantified fixed substring with a large minimum count, the byte length mincount * l could overflow SSize_t, producing an undersized SvGROW allocation; the subsequent copy writes past the end of the buffer.
A caller that compiles an attacker-controlled regular expression on a 32-bit perl build triggers a heap buffer overflow at compile time.
