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: ata: pata_macio: Fix DMA table     overflow Kolbjrn and Jon reported that their 32-bit PowerMacs were crashing in pata-macio since commit     09fe2bfa6b83 (ata: pata_macio: Fix max_segment_size with PAGE_SIZE == 64K). For example: kernel BUG at     drivers/ata/pata_macio.c:544! Oops: Exception in kernel mode, sig: 5 [#1] BE PAGE_SIZE=4K MMU=Hash SMP     NR_CPUS=2 DEBUG_PAGEALLOC PowerMac ...

    However with a sufficiently large request, the splitting logic causes each sg to be split into two     commands in the DMA table, leading to overflow of the DMA table, triggering the BUG_ON(). With default     settings the bug doesn't trigger, because the request size is limited by max_sectors_kb == 1280, however     max_sectors_kb can be increased, and apparently some distros do that by default using udev rules. Fix the     bug for 4KB kernels by reverting to the old max_segment_size. For 64KB kernels the sg_tablesize needs to     be halved, to allow for the possibility that each sg will be split into two. (CVE-2024-44976)

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