CVE-2026-57432 Perl versions through 5.43.10 have an integer overflow in S_measure_struct leading to an out-of-bounds heap read in pack and unpack

Perl versions through 5.43.10 have an integer overflow in Smeasurestruct leading to an out-of-bounds heap read in pack and unpack. Smeasurestruct adds each item's size times its repeat count to a running total with no overflow check, so a large repeat count in a pack or unpack template wraps the...

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...
