The remote Scientific Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the SLSA-2023:0399-1 advisory.

  • kernel: memory corruption in AX88179_178A based USB ethernet device. (CVE-2022-2964)

  • hw: cpu: LFENCE/JMP Mitigation Update for CVE-2017-5715 (CVE-2021-26401)

Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
