CVE-2026-2474

Crypt::URandom versions from 0.41 before 0.55 for Perl is vulnerable to a heap buffer overflow in the XS function crypt_urandom_getrandom(). The function does not validate that the length parameter is non-negative. If a negative value (e.g. -1) is supplied, the expression length + 1u causes an integer wraparound, resulting in a zero-byte allocation. The subsequent call to getrandom(data, length, GRND_NONBLOCK) passes the original negative value, which is implicitly converted to a large unsigned
