There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - In the Linux kernel, the following vulnerability has been resolved: slub: fix data loss and overflow in
    krealloc() Commit 2cd8231796b5 ("mm/slub: allow to set node and align in k[v]realloc") introduced the
    ability to force a reallocation if the original object does not satisfy new alignment or NUMA node, even
    when the object is being shrunk. This introduced two bugs in the reallocation fallback path: 1. Data loss
    during NUMA migration: The jump to 'alloc_new' happens before 'ks' and 'orig_size' are initialized. As a
    result, the memcpy() in the 'alloc_new' block would copy 0 bytes into the new allocation. 2. Buffer
    overflow during shrinking: When shrinking an object while forcing a new alignment, 'new_size' is smaller
    than the old size. However, the memcpy() used the old size ('orig_size ?: ks'), leading to an out-of-
    bounds write. The same overflow bug exists in the kvrealloc() fallback path, where the old bucket size
    ksize(p) is copied into the new buffer without being bounded by the new size. A simple reproducer: // e.g.
    add to lkdtm as KREALLOC_SHRINK_OVERFLOW while (1) { void *p = kmalloc(128, GFP_KERNEL); p =
    krealloc_node_align(p, 64, 256, GFP_KERNEL, NUMA_NO_NODE); kfree(p); } demonstrates the issue:

    Fix it by moving the old size calculation to the top of __do_krealloc() and bounding all copy lengths by
    the new allocation size. (CVE-2026-45990)

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)

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

  - In the Linux kernel, the following vulnerability has been resolved: slub: fix data loss and overflow in     krealloc() Commit 2cd8231796b5 (mm/slub: allow to set node and align in k[v]realloc) introduced the     ability to force a reallocation if the original object does not satisfy new alignment or NUMA node, even     when the object is being shrunk. This introduced two bugs in the reallocation fallback path: 1. Data loss     during NUMA migration: The jump to 'alloc_new' happens before 'ks' and 'orig_size' are initialized. As a     result, the memcpy() in the 'alloc_new' block would copy 0 bytes into the new allocation. 2. Buffer     overflow during shrinking: When shrinking an object while forcing a new alignment, 'new_size' is smaller     than the old size. However, the memcpy() used the old size ('orig_size ?: ks'), leading to an out-of-     bounds write. The same overflow bug exists in the kvrealloc() fallback path, where the old bucket size     ksize(p) is copied into the new buffer without being bounded by the new size. A simple reproducer: // e.g.
    add to lkdtm as KREALLOC_SHRINK_OVERFLOW while (1) { void *p = kmalloc(128, GFP_KERNEL); p =     krealloc_node_align(p, 64, 256, GFP_KERNEL, NUMA_NO_NODE); kfree(p); } demonstrates the issue:

The remote Ubuntu 26.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8507-1 advisory.

    It was discovered that some AMD processors did not properly clear data in the floating point divider unit     during speculative execution. A local attacker could use this to expose sensitive information.
