In the Linux kernel, the following vulnerability has been resolved: net: liquidio: Initialize netdev pointer before queue setup In setup_nic_devices(), the netdev is allocated using alloc_etherdev_mq(). However, the pointer to this structure is stored in oct->props[i].netdev only after the calls to netif_set_real_num_rx_queues() and netif_set_real_num_tx_queues(). If either of these functions fails, setup_nic_devices() returns an error without freeing the allocated netdev. Since oct->props[i].netdev is still NULL at this point, the cleanup function liquidio_destroy_nic_device() will fail to find and free the netdev, resulting in a memory leak. Fix this by initializing oct->props[i].netdev before calling the queue setup functions. This ensures that the netdev is properly accessible for cleanup in case of errors. Compile tested only. Issue found using a prototype static analysis tool and code review.

The remote Ubuntu 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8440-1 advisory.

    Josh Eads, Kristoffer Janke, Eduardo Vela Nava, Tavis Ormandy, and Matteo Rizzo discovered that some AMD     Zen processors did not properly verify the signature of CPU microcode. This flaw is known as EntrySign. A     privileged attacker could possibly use this issue to cause load malicious CPU microcode causing loss of     integrity and confidentiality. (CVE-2024-36347)

    It was discovered that the Linux kernel algif_aead module did not properly handle in-place cryptographic     operations. This flaw is known as Copy Fail. A local attacker could use this to escalate privileges, or     possibly escape a container. (CVE-2026-31431)

    It was discovered that the Linux kernel did not properly handle shared page fragments during socket buffer     operations, collectively known as Dirty Frag. A logic flaw existed in the XFRM ESP-in-TCP subsystem and in     the RxRPC networking subsystem when processing paged fragments. A local attacker could use this to     escalate privileges, or possibly escape a container. (CVE-2026-43284, CVE-2026-43500, CVE-2026-45998,     CVE-2026-46000)

    It was discovered that a logic flaw existed in the XFRM ESP-in-TCP subsystem in the Linux kernel when     handling socket buffer fragments. This flaw is known as Fragnesia. A local attacker could use this to     escalate privileges, or possibly escape a container. (CVE-2026-43503, CVE-2026-46300)

    Qualys discovered that a race condition existed in the ptrace subsystem of the Linux kernel when     privileged processes are exiting. An unprivileged local attacker could use this issue to expose sensitive     information. (CVE-2026-46333)

    Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 contain a memory leak when handling     AppArmor notifications. A local attacker could use this to cause resource exhaustion. (CVE-2026-47326)

    Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 contain a NULL pointer dereference     when handling AppArmor notifications. A local attacker could use this to cause a kernel oops.
    (CVE-2026-47327)

    Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 contained an invalid free when     handling AppArmor notifications. A local attacker could use this to corrupt kernel memory.
    (CVE-2026-47328)

    Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 contained insufficient validation of     AppArmor notification responses. A local attacker could use this to allow crafted responses to be     processed. (CVE-2026-47329)

    Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 used an uninitialized variable when     handling AppArmor notifications. A local attacker could use this to cause incorrect caching of data.
    (CVE-2026-47330)

    Tristan Madani discovered that Ubuntu Linux kernel 6.8 contained a use- after-free (UAF) bug. A local     attacker could use this to cause memory corruption and, theoretically, arbitrary code execution.
    (CVE-2026-47331)

    Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 contained an out-of-bounds (OOB) read     when handling AppArmor notifications. A local attacker could use this to cause information disclosure of     kernel memory. (CVE-2026-47332)

    Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 contained a out-of-bounds (OOB) read     when handling AppArmor notifications. A local attacker could use this to cause kernel memory corruption     and, theoretically, influence processing of AppArmor policies. (CVE-2026-47333)

    Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 contained incorrect holding of locks     when handling AppArmor notifications. A local attacker could use this to cause a kernel panic or deadlock.
    (CVE-2026-47334)

    Tristan Madani discovered that Ubuntu Linux kernel 6.8 contained a NULL pointer dereference when handling     AppArmor notifications. A local attacker could use this to cause a kernel panic. (CVE-2026-47335)

    Tristan Madani discovered that Ubuntu Linux kernel 6.8 used an uninitialized variable when handling     AppArmor AF_INET/AF_INET6 socket mediation. A local attacker could use this to influence processing of     fine- grained network socket mediation. (CVE-2026-47336)

    Tristan Madani and Trevor Lawrence have each independently discovered that Ubuntu Linux kernel 6.8, 6.17     and 7.0 contained a NULL pointer dereference when handling AppArmor network socket mediation. A local     attacker could use this to cause a kernel oops. (CVE-2026-47337)

The remote Ubuntu 24.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8393-1 advisory.

    It was discovered that the Linux kernel algif_aead module did not properly handle in-place cryptographic     operations. This flaw is known as Copy Fail. A local attacker could use this to escalate privileges, or     possibly escape a container. (CVE-2026-31431)

    It was discovered that the Linux kernel did not properly handle shared page fragments during socket buffer     operations, collectively known as Dirty Frag. A logic flaw existed in the XFRM ESP-in-TCP subsystem and in     the RxRPC networking subsystem when processing paged fragments. A local attacker could use this to     escalate privileges, or possibly escape a container. (CVE-2026-43284, CVE-2026-43500, CVE-2026-45998,     CVE-2026-46000)

    It was discovered that a logic flaw existed in the XFRM ESP-in-TCP subsystem in the Linux kernel when     handling socket buffer fragments. This flaw is known as Fragnesia. A local attacker could use this to     escalate privileges, or possibly escape a container. (CVE-2026-43503, CVE-2026-46300)

    Qualys discovered that a race condition existed in the ptrace subsystem of the Linux kernel when     privileged processes are exiting. An unprivileged local attacker could use this issue to expose sensitive     information. (CVE-2026-46333)

    Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 contain a memory leak when handling     AppArmor notifications. A local attacker could use this to cause resource exhaustion. (CVE-2026-47326)

    Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 contain a NULL pointer dereference     when handling AppArmor notifications. A local attacker could use this to cause a kernel oops.
    (CVE-2026-47327)

    Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 contained an invalid free when     handling AppArmor notifications. A local attacker could use this to corrupt kernel memory.
    (CVE-2026-47328)

    Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 contained insufficient validation of     AppArmor notification responses. A local attacker could use this to allow crafted responses to be     processed. (CVE-2026-47329)

    Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 used an uninitialized variable when     handling AppArmor notifications. A local attacker could use this to cause incorrect caching of data.
    (CVE-2026-47330)

    Tristan Madani discovered that Ubuntu Linux kernel 6.8 contained a use- after-free (UAF) bug. A local     attacker could use this to cause memory corruption and, theoretically, arbitrary code execution.
    (CVE-2026-47331)

    Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 contained an out-of-bounds (OOB) read     when handling AppArmor notifications. A local attacker could use this to cause information disclosure of     kernel memory. (CVE-2026-47332)

    Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 contained a out-of-bounds (OOB) read     when handling AppArmor notifications. A local attacker could use this to cause kernel memory corruption     and, theoretically, influence processing of AppArmor policies. (CVE-2026-47333)

    Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 contained incorrect holding of locks     when handling AppArmor notifications. A local attacker could use this to cause a kernel panic or deadlock.
    (CVE-2026-47334)

    Tristan Madani discovered that Ubuntu Linux kernel 6.8 contained a NULL pointer dereference when handling     AppArmor notifications. A local attacker could use this to cause a kernel panic. (CVE-2026-47335)

    Tristan Madani discovered that Ubuntu Linux kernel 6.8 used an uninitialized variable when handling     AppArmor AF_INET/AF_INET6 socket mediation. A local attacker could use this to influence processing of     fine- grained network socket mediation. (CVE-2026-47336)

    Tristan Madani and Trevor Lawrence have each independently discovered that Ubuntu Linux kernel 6.8, 6.17     and 7.0 contained a NULL pointer dereference when handling AppArmor network socket mediation. A local     attacker could use this to cause a kernel oops. (CVE-2026-47337)

Tenable has extracted the preceding description block directly from the Ubuntu 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: liquidio: Initialize netdev pointer before queue setup In setup_nic_devices(), the netdev is     allocated using alloc_etherdev_mq(). However, the pointer to this structure is stored in     oct->props[i].netdev only after the calls to netif_set_real_num_rx_queues() and     netif_set_real_num_tx_queues(). If either of these functions fails, setup_nic_devices() returns an error     without freeing the allocated netdev. Since oct->props[i].netdev is still NULL at this point, the cleanup     function liquidio_destroy_nic_device() will fail to find and free the netdev, resulting in a memory leak.
    Fix this by initializing oct->props[i].netdev before calling the queue setup functions. This ensures that     the netdev is properly accessible for cleanup in case of errors. Compile tested only. Issue found using a     prototype static analysis tool and code review. (CVE-2026-23258)

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

An update of the linux package has been released.
