Libsodium · Libsodium · CVE-2026-2588
**Name of the Vulnerable Software and Affected Versions**
Crypt::NaCl::Sodium versions through 2.001
**Description**
The software contains an integer overflow flaw on 32-bit systems. Specifically, the Sodium.xs component casts a `STRLEN` (size t) to an 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.
**Recommendations**
Update to a version of Crypt::NaCl::Sodium later than 2.001.
