CVE-2026-15534

CVE-2026-15534 affects Perl up to version 5.45.1. The vulnerability is in the regex engine’s S_regmatch component: an undersized superlinear cache allows out-of-bounds heap reads and writes during pattern matching. The cache counts are computed as subject length times participating WHILEM nodes, ...
