Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

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

  - xsk: Fix fragment node deletion to prevent buffer leak After commit b692bf9a7543 (xsk: Get rid of     xdp_buff_xsk::xskb_list_node), the list_node field is reused for both the xskb pool list and the buffer     free list, this causes a buffer leak as described below. xp_free() checks if a buffer is already on the     free list using list_empty(&xskb->list_node). When list_del() is used to remove a node from the xskb pool     list, it doesn't reinitialize the node pointers. This means list_empty() will return false even after the     node has been removed, causing xp_free() to incorrectly skip adding the buffer to the free list. Fix this     by using list_del_init() instead of list_del() in all fragment handling paths, this ensures the list node     is reinitialized after removal, allowing the list_empty() to work correctly. (CVE-2026-23326)

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

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1596 advisory.
