Synopsis

Description

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

A use-after-free vulnerability has been identified in the GNU GRUB (Grand Unified Bootloader). The flaw occurs because the file-closing process incorrectly retains a memory pointer, leaving an invalid reference to a file system structure. An attacker could exploit this vulnerability to cause grub to crash, leading to a Denial of Service. Possible data integrity or confidentiality compromise is not discarded.(CVE-2025-54771)

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.
