In the Linux kernel, the following vulnerability has been resolved: net: add proper RCU protection to /proc/net/ptype Yin Fengwei reported an RCU stall in ptype_seq_show() and provided a patch. Real issue is that ptype_seq_next() and ptype_seq_show() violate RCU rules. ptype_seq_show() runs under rcu_read_lock(), and reads pt->dev to get device name without any barrier. At the same time, concurrent writers can remove a packet_type structure (which is correctly freed after an RCU grace period) and clear pt->dev without an RCU grace period. Define ptype_iter_state to carry a dev pointer along seq_net_private: struct ptype_iter_state { struct seq_net_private p; struct net_device *dev; // added in this patch }; We need to record the device pointer in ptype_get_idx() and ptype_seq_next() so that ptype_seq_show() is safe against concurrent pt->dev changes. We also need to add full RCU protection in ptype_seq_next(). (Missing READ_ONCE() when reading list.next values) Many thanks to Dong Chenchen for providing a repro.

    Several vulnerabilities have been discovered in the Linux kernel that     may lead to a privilege escalation, denial of service or information     leaks.

    For the stable distribution (trixie), these problems have been fixed in     version 6.12.85-1.

    We recommend that you upgrade your linux packages.

    For the detailed security status of linux please refer to its security     tracker page at:

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.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1514 advisory.

    In the Linux kernel, the following vulnerability has been resolved:

    btrfs: fix reservation leak in some error paths when inserting inline extent (CVE-2025-71268)

    tracing/dma: Cap dma_map_sg tracepoint arrays to prevent buffer overflow (CVE-2026-23390)

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.

  - net: add proper RCU protection to /proc/net/ptype Yin Fengwei reported an RCU stall in ptype_seq_show()     and provided a patch. Real issue is that ptype_seq_next() and ptype_seq_show() violate RCU rules.
    ptype_seq_show() runs under rcu_read_lock(), and reads pt->dev to get device name without any barrier. At     the same time, concurrent writers can remove a packet_type structure (which is correctly freed after an     RCU grace period) and clear pt->dev without an RCU grace period. Define ptype_iter_state to carry a dev     pointer along seq_net_private: struct ptype_iter_state { struct seq_net_private p; struct net_device *dev;
    // added in this patch }; We need to record the device pointer in ptype_get_idx() and ptype_seq_next() so     that ptype_seq_show() is safe against concurrent pt->dev changes. We also need to add full RCU protection     in ptype_seq_next(). (Missing READ_ONCE() when reading list.next values) Many thanks to Dong Chenchen for     providing a repro. (CVE-2026-23255)

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