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

  - scsi: megaraid_sas: Limit NVMe request size to the PRP chain frame megasas_make_prp_nvme() builds a     command's PRP list in cmd->sg_frame, a DMA pool buffer of instance->max_chain_frame_sz bytes, spending one     entry per NVMe page of the transfer plus one per page of the buffer for the chain pointer. The loop runs     until the transfer is described and never checks the buffer bound. max_hw_sectors comes straight from the     MDTS the firmware reports for the drive. On drives with a large MDTS the only thing keeping the list     inside the buffer was the block layer default of 1280 KiB, which needs 320 entries, which fit into a 4 KiB     frame as that holds 512. But since commit 9b8b84879d4a (block: Increase BLK_DEF_MAX_SECTORS_CAP) that     default is 4 MiB, and such a transfer needs 1025 entries, so the list runs a full page past the end of the     frame: sd 1:0:1:0: [sdb] tag#630 page boundary ptr_sgl: 0x00000000ba62d13f BUG: unable to handle page     fault for address: ff663bcb81e7c000 #PF: supervisor write access in kernel mode #PF: error_code(0x0002) -     not-present page RIP: 0010:megasas_build_and_issue_cmd_fusion+0xeaa/0x1870 [megaraid_sas] If the page     after the frame happens to be mapped, the overrun does not fault but silently corrupts the neighbouring     pool entry, which is another in-flight command's PRP list. Cap max_hw_sectors at what the chain frame can     describe, less one page for transfers that do not start on a page boundary and so need one entry more.
    This is the megaraid_sas counterpart of commit 04631f55afc5 (scsi: mpt3sas: Limit NVMe request size to 2     MiB), but derives the limit from max_chain_frame_sz rather than hardcoding it. (CVE-2026-90008)

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