CVE-2026-57433

CVE-2026-57433 affects Perl’s Storable before 3.41. A signed 32-bit item count read from an SX_HOOK record is added to one and then fed to av_extend; when the count equals I32_MAX the addition overflows to negative, causing av_extend to panic during thaw/retrieve and terminate deserialization. Mu...
