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

  - ALSA: ctxfi: Limit PTP to a single page Commit 391e69143d0a increased CT_PTP_NUM from 1 to 4 to support     256 playback streams, but the additional pages are not used by the card correctly. The CT20K2 hardware     already has multiple VMEM_PTPAL registers, but using them separately would require refactoring the entire     virtual memory allocation logic. ct_vm_map() always uses PTEs in vm->ptp[0].area regardless of CT_PTP_NUM.
    On AMD64 systems, a single PTP covers 512 PTEs (2M). When aggregate memory allocations exceed this limit,     ct_vm_map() tries to access beyond the allocated space and causes a page fault: BUG: unable to handle page     fault for address: ffffd4ae8a10a000 Oops: Oops: 0002 [#1] SMP PTI RIP: 0010:ct_vm_map+0x17c/0x280     [snd_ctxfi] Call Trace: atc_pcm_playback_prepare+0x225/0x3b0 ct_pcm_playback_prepare+0x38/0x60     snd_pcm_do_prepare+0x2f/0x50 snd_pcm_action_single+0x36/0x90 snd_pcm_action_nonatomic+0xbf/0xd0     snd_pcm_ioctl+0x28/0x40 __x64_sys_ioctl+0x97/0xe0 do_syscall_64+0x81/0x610     entry_SYSCALL_64_after_hwframe+0x76/0x7e Revert CT_PTP_NUM to 1. The 256 SRC_RESOURCE_NUM and     playback_count remain unchanged. (CVE-2026-31602)

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