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: drm/xe/uapi: Reject coh_none PAT index     for CPU cached memory in madvise Add validation in xe_vm_madvise_ioctl() to reject PAT indices with     XE_COH_NONE coherency mode when applied to CPU cached memory. Using coh_none with CPU cached buffers is a     security issue. When the kernel clears pages before reallocation, the clear operation stays in CPU cache     (dirty). GPU with coh_none can bypass CPU caches and read stale sensitive data directly from DRAM,     potentially leaking data from previously freed pages of other processes. This aligns with the existing     validation in vm_bind path (xe_vm_bind_ioctl_validate_bo). v2(Matthew brost) - Add fixes - Move one debug     print to better place v3(Matthew Auld) - Should be drm/xe/uapi - More Cc v4(Shuicheng Lin) - Fix kmem leak     issues by the way v5 - Remove kmem leak because it has been merged by another patch v6 - Remove the fix     which is not related to current fix v7 - No change v8 - Rebase v9 - Limit the restrictions to iGPU v10 -     No change (cherry picked from commit 016ccdb674b8c899940b3944952c96a6a490d10a) (CVE-2026-46309)

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