In the Linux kernel, the following vulnerability has been resolved: netfilter: nfnetlink_log: wait for rcu grace period before freeing pernet state sashiko reports: "nfnl_log_net_exit() calls nf_log_unset(), which clears the logger pointer without an RCU grace period. Immediately after, ops_free_list() frees the per-net state while concurrent packets might still be executing nf_log_packet() under rcu_read_lock()." Clear the pointer via .pre_exit to make sure rcu readers have completed before pernet storage is free'd. The change in nf_log_syslog.c is only done for consistency: it doesn't use pernet data.

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

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

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-3192 advisory.

    An issue in the Linux kernel's virtio-net/TAP networking path could allow an actor with privileged access     inside a guest virtual machine to send specially crafted network packets that corrupt host kernel memory     on KVM-based hypervisors running unpatched Linux kernel versions 4.4 through 6.18. This could result in     disclosure of host memory or a denial of service.

Tenable has extracted the preceding description block directly from the tested product 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.

  - netfilter: nfnetlink_log: wait for rcu grace period before freeing pernet state sashiko reports:
    nfnl_log_net_exit() calls nf_log_unset(), which clears the logger pointer without an RCU grace period.
    Immediately after, ops_free_list() frees the per-net state while concurrent packets might still be     executing nf_log_packet() under rcu_read_lock(). Clear the pointer via .pre_exit to make sure rcu readers     have completed before pernet storage is free'd. The change in nf_log_syslog.c is only done for     consistency: it doesn't use pernet data. (CVE-2026-93288)

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