CVE-2026-116587: Go Rsa Private Key Validate Without Size And Consistency Bounds
An rsa.PrivateKey is assembled from parsed values and passed to Validate()/Precompute() without first bounding the modulus size (e.g. if $n.BitLen() > limit) and checking p * q == n. When the key material originates from untrusted input (JSON/JWK/protocol fields), crafted large or degenerate RSA parameters make validation consume cubic CPU time on Go 1.24+,
