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

  - net/mlx5e: xsk: Fix DMA and xdp_frame leak on XDP_TX xmit failure In the XSK branch of     mlx5e_xmit_xdp_buff(), when sq->xmit_xdp_frame() returns false (e.g. XDPSQ is full), the function returns     without unmapping the DMA address or freeing the xdp_frame allocated by xdp_convert_zc_to_xdp_frame(). The     xdpi_fifo push only happens on success, so the completion path cannot recover these entries. With     CONFIG_DMA_API_DEBUG=y, the leak surfaces on driver unbind: DMA-API: pci 0000:08:00.0: device driver has     pending DMA allocations while released from device [count=1116] One of leaked entries details: [device     address=0x000000010ffd7028] [size=1534 bytes] [mapped with DMA_TO_DEVICE] [mapped as phy] WARNING:

    (CVE-2026-53229)

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