An update of the linux package has been released.

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

  - net/smc: unregister the connection before draining the rx tasklet smc_conn_free() calls     smc_ism_unset_conn() only while the link group is still on its device list, and never sets conn->killed.
    smc_lgr_terminate_sched() unlinks the group immediately and defers killing its connections to a work item,     so a connection freed in that window keeps its smcd->conn[] slot with both gates in smcd_handle_irq()     open, and the device can re-arm the receive tasklet after tasklet_kill() has returned. On the DMB-nocopy     path the ghost send buffer is freed right after that drain, so the re-armed tasklet dereferences it.
    Unregister unconditionally and drain before the detach at both teardown sites, mirroring rmb_desc, which     smc_buf_unuse() releases after the drain. Clear conn->sndbuf_desc before freeing it as well, so a reader     that samples the pointer cannot get one that is already freed. (CVE-2026-80979)

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