The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - In the Linux kernel, the following vulnerability has been resolved: kernfs: fix potential NULL dereference     in __kernfs_remove When lockdep is enabled, lockdep_assert_held_write would cause potential NULL pointer     dereference. Fix the following smatch warnings: fs/kernfs/dir.c:1353 __kernfs_remove() warn: variable     dereferenced before check 'kn' (see line 1346) (CVE-2022-50148)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:1404 advisory.

    The kernel packages contain the Linux kernel, the core of any Linux operating system.
