According to the versions of the grub2 packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

    GNU GRUB (aka GRUB2) through 2.12 does not use a constant-time algorithm for grub_crypto_memcmp and thus     allows side-channel attacks.(CVE-2024-56738)

Tenable has extracted the preceding description block directly from the EulerOS grub2 security advisory.

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