CVE-2026-2588
February 22, 2026
Crypt::NaCl::Sodium versions through 2.001 for Perl has an integer overflow flaw on 32-bit systems. Sodium.xs casts a STRLEN (size_t) to unsigned long long when passing a length pointer to libsodium functions. On 32-bit systems size_t is typically 32-bits while an unsigned long long is at least 64-bits.
