Name of the Vulnerable Software and Affected Versions Nettle versions prior to 3.2

Description The issue is related to the x86 64/ecc-384-modp.asm function in the Nettle cryptographic library, which incorrectly handles carry propagation and produces incorrect output in its implementation of the P-384 NIST elliptic curve. This allows attackers to have an unspecified impact via unknown vectors, potentially affecting the confidentiality, integrity, and availability of protected information.
