"According to the versions of the golang packages installed, the EulerOS installation on the remote host is affected by
the following vulnerabilities :

    Due to the usage of a variable time instruction in the assembly implementation of an internal function, a
    small number of bits of secret scalars are leaked on the ppc64le architecture. Due to the way this
    function is used, we do not believe this leakage is enough to allow recovery of the private key when P-256
    is used in any well known protocols.(CVE-2025-22866)

Tenable has extracted the preceding description block directly from the EulerOS golang security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
