The remote Ubuntu 24.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8499-1 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 remote Ubuntu 26.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8489-1 advisory.

    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, 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 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)
