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

  - media: em28xx: fix use-after-free of dev_next->devlist on disconnect When a device with has_dual_ts=1 is     probed and the is_audio_only path is taken, both dev and dev->dev_next are added to the global     em28xx_devlist via em28xx_init_extension(). However, during disconnect, em28xx_close_extension(dev) only     calls list_del(&dev->devlist), leaving dev->dev_next->devlist still linked in the global list. When     dev_next is subsequently freed via kref_put(), its devlist entry becomes a dangling pointer in     em28xx_devlist. The next device probe that calls em28xx_init_extension() triggers a list corruption BUG     when list_add_tail detects the freed node. This bug was exposed by commit a368ecde8a50 (USB: core: Fix     duplicate endpoint bug by clearing reserved bits in the descriptor) which clears reserved bits in     bEndpointAddress during endpoint parsing. This causes fuzzed endpoint addresses like 0xf3 to be normalized     to 0x83, which em28xx interprets as a vendor audio endpoint, enabling the is_audio_only + has_dual_ts code     path that was previously unreachable with such descriptors. Fix this by removing dev->dev_next->devlist     from the global list in em28xx_close_extension() before the device is freed. (CVE-2026-89891)

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