An update of the linux package has been released.

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/32: Fix hardlockup on vmap     stack overflow Since the commit c118c7303ad5 (powerpc/32: Fix vmap stack - Do not activate MMU before     reading task struct) a vmap stack overflow results in a hard lockup. This is because emergency_ctx is     still addressed with its virtual address allthough data MMU is not active anymore at that time. Fix it by     using a physical address instead. (CVE-2021-47567)

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