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

  - dmaengine: mmp_pdma: Fix race condition in mmp_pdma_residue() Add proper locking in mmp_pdma_residue() to     prevent use-after-free when accessing descriptor list and descriptor contents. The race occurs when     multiple threads call tx_status() while the tasklet on another CPU is freeing completed descriptors: CPU 0     CPU 1 ----- ----- mmp_pdma_tx_status() mmp_pdma_residue() -> NO LOCK held list_for_each_entry(sw, ..) DMA     interrupt dma_do_tasklet() -> spin_lock(&desc_lock) list_move(sw->node, ...) spin_unlock(&desc_lock) |     dma_pool_free(sw) <- FREED! -> access sw->desc <- UAF! This issue can be reproduced when running dmatest     on the same channel with multiple threads (threads_per_chan > 1). Fix by protecting the chain_running list     iteration and descriptor access with the chan->desc_lock spinlock. (CVE-2025-71221)

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