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

  - ARM: 9485/1: mm: acquire mmap write lock around show_pte() for user faults When CONFIG_DEBUG_USER=y, and     cmdline user_debug=31 is set, a user fault may trigger show_pte() without any lock. If another thread in     the same process concurrently calls munmap(), the page table pages may be freed while show_pte() is still     traversing them, causing a use-after-free in show_pte(). If CONFIG_ARM_LPAE=y, this may cause a kernel     panic if the pages table of PMD are freed when show_pte() is running. Acquire mmap_write_lock() around     show_pte() for user faults to fix the contention. For user faults, additionally restrict that show_pte()     is called only when the addr is a user-space address (addr < TASK_SIZE). This is because the lock of     tsk->mm only protects the virtual memory of user address space, furthermore, dumping the page tables of a     kernel-space address for user faults is unnecessary and may have security implications. Keep everything     unchanged for kernel faults, because the kernel is already in the oops state, acquiring a lock may risk     a deadlock. (CVE-2026-90303)

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