The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2022:6003 advisory.

  • kernel: information leak in scsi_ioctl() (CVE-2022-0494)

  • kernel: use-after-free in tc_new_tfilter() in net/sched/cls_api.c (CVE-2022-1055)

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