DEBIAN-CVE-2026-57433

Storable versions before 3.41 for Perl have a signed integer overflow when deserializing a crafted SX_HOOK record.

Storable versions before 3.41 for Perl have a signed integer overflow when deserializing a crafted SXHOOK record.  retrievehookcommon reads a signed 32-bit item count from an SXHOOK record and calls avextend with that count plus one. A count of I32MAX wraps the addition to a negative value.  A crafted blob passed to thaw or retrieve triggers the overflow; av_extend receives the negative count and dies with a panic, terminating the deserialization.
