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

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

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: powerpc/64: Fix the definition of the     fixmap area At the time being, the fixmap area is defined at the top of the address space or just below     KASAN. This definition is not valid for PPC64. For PPC64, use the top of the I/O space. Because of     circular dependencies, it is not possible to include asm/fixmap.h in asm/book3s/64/pgtable.h , so define a     fixed size AREA at the top of the I/O space for fixmap and ensure during build that the size is big     enough. (CVE-2021-47018)

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