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/pci: Fix get_phb_number()     locking The recent change to get_phb_number() causes a DEBUG_ATOMIC_SLEEP warning on some systems: BUG:
    sleeping function called from invalid context at kernel/locking/mutex.c:580 in_atomic(): 1,     irqs_disabled(): 0, non_block: 0, pid: 1, name: swapper preempt_count: 1, expected: 0 RCU nest depth: 0,     expected: 0 1 lock held by swapper/1: #0: c157efb0 (hose_spinlock){+.+.}-{2:2}, at:

The hose_spinlock protects the phb_bitmap, and also the     hose_list, but it doesn't need to be held while get_phb_number() calls the OF routines, because those are     only looking up information in the device tree. So fix it by having get_phb_number() take the     hose_spinlock itself, only where required, and then dropping the lock before returning.
    pcibios_alloc_controller() then needs to take the lock again before the list_add() but that's safe, the     order of the list is not important. (CVE-2022-50045)

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