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: net/smc: fix qentry overwrite for     CONFIRM_LINK and ADD_LINK_CONT in smc_llc_event_handler() The SMC_LLC_CONFIRM_LINK / SMC_LLC_ADD_LINK_CONT     branch in smc_llc_event_handler() stores an incoming qentry into the local LLC flow without first checking     whether a qentry is already pending. If a malicious or buggy peer sends a second CONFIRM_LINK or     ADD_LINK_CONT request while a flow is active and flow->qentry is already set, smc_llc_flow_qentry_set()     overwrites the pointer without freeing the previous allocation, leaking one kmalloc-96 object per spurious     message. The sibling SMC_LLC_DELETE_LINK branch already has the correct !flow->qentry guard. Apply the     same guard to the CONFIRM_LINK/ADD_LINK_CONT branch so that a duplicate message when qentry is already     occupied falls through to break and is freed by the kfree(qentry) at the out: label, rather than silently     leaking the existing allocation. The response direction (smc_llc_rx_response()) is unaffected: it already     guards with flow->qentry at the equivalent site and drops duplicate responses correctly. (CVE-2026-74719)

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