The remote Ubuntu 24.04 LTS / 25.10 host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8094-1 advisory.

    Qualys discovered that several vulnerabilities existed in the AppArmor Linux kernel Security Module (LSM).
    An unprivileged local attacker could use these issues to load, replace, and remove arbitrary AppArmor     profiles causing denial of service, exposure of sensitive information (kernel memory), local privilege     escalation, or possibly escape a container. (LP: #2143853)

    It was discovered that some AMD Zen 5 processors supporting RDSEED instruction did not properly handle     entropy, potentially resulting in the consumption of insufficiently random values. A local attacker could     possibly use this issue to influence the values returned by the RDSEED instruction causing loss of     confidentiality and integrity. (CVE-2025-62626)

The remote CentOS Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the kernel-5.14.0-704.el9 build changelog.

  - In the Linux kernel, the following vulnerability has been resolved: iommu: disable SVA when CONFIG_X86 is     set Patch series Fix stale IOTLB entries for kernel address space, v7. This proposes a fix for a     security vulnerability related to IOMMU Shared Virtual Addressing (SVA). In an SVA context, an IOMMU can     cache kernel page table entries. When a kernel page table page is freed and reallocated for another     purpose, the IOMMU might still hold stale, incorrect entries. This can be exploited to cause a use-after-     free or write-after-free condition, potentially leading to privilege escalation or data corruption. This     solution introduces a deferred freeing mechanism for kernel page table pages, which provides a safe window     to notify the IOMMU to invalidate its caches before the page is reused. This patch (of 8): In the IOMMU     Shared Virtual Addressing (SVA) context, the IOMMU hardware shares and walks the CPU's page tables. The     x86 architecture maps the kernel's virtual address space into the upper portion of every process's page     table. Consequently, in an SVA context, the IOMMU hardware can walk and cache kernel page table entries.
    The Linux kernel currently lacks a notification mechanism for kernel page table changes, specifically when     page table pages are freed and reused. The IOMMU driver is only notified of changes to user virtual     address mappings. This can cause the IOMMU's internal caches to retain stale entries for kernel VA. Use-     After-Free (UAF) and Write-After-Free (WAF) conditions arise when kernel page table pages are freed and     later reallocated. The IOMMU could misinterpret the new data as valid page table entries. The IOMMU might     then walk into attacker-controlled memory, leading to arbitrary physical memory DMA access or privilege     escalation. This is also a Write-After-Free issue, as the IOMMU will potentially continue to write     Accessed and Dirty bits to the freed memory while attempting to walk the stale page tables. Currently, SVA     contexts are unprivileged and cannot access kernel mappings. However, the IOMMU will still walk kernel-     only page tables all the way down to the leaf entries, where it realizes the mapping is for the kernel and     errors out. This means the IOMMU still caches these intermediate page table entries, making the described     vulnerability a real concern. Disable SVA on x86 architecture until the IOMMU can receive notification to     flush the paging cache before freeing the CPU kernel page table pages. (CVE-2025-71089)

  - In the Linux kernel, the following vulnerability has been resolved: md: init bioset in mddev_init IO     operations may be needed before md_run(), such as updating metadata after writing sysfs. Without bioset,     this triggers a NULL pointer dereference as below: BUG: kernel NULL pointer dereference, address:

  - In the Linux kernel, the following vulnerability has been resolved: md: avoid repeated calls to     del_gendisk There is a uaf problem which is found by case 23rdev-lifetime: Oops: general protection fault,     probably for non-canonical address 0xdead000000000122 RIP: 0010:bdi_unregister+0x4b/0x170 Call Trace:

This     patch adds a flag MD_DO_DELETE to avoid the race condition. (CVE-2025-68373)

  - In the Linux kernel, the following vulnerability has been resolved: md: fix rcu protection in     md_wakeup_thread We attempted to use RCU to protect the pointer 'thread', but directly passed the value     when calling md_wakeup_thread(). This means that the RCU pointer has been acquired before rcu_read_lock(),     which renders rcu_read_lock() ineffective and could lead to a use-after-free. (CVE-2025-68374)

  - In the Linux kernel, the following vulnerability has been resolved: md/raid5: fix possible null-pointer     dereferences in raid5_store_group_thread_cnt() The variable mddev->private is first assigned to conf and     then checked: conf = mddev->private; if (!conf) ... If conf is NULL, then mddev->private is also NULL. In     this case, null-pointer dereferences can occur when calling raid5_quiesce(): raid5_quiesce(mddev, true);
    raid5_quiesce(mddev, false); since mddev->private is assigned to conf again in raid5_quiesce(), and conf     is dereferenced in several places, for example: conf->quiesce = 0; wake_up(&conf->wait_for_quiescent); To     fix this issue, the function should unlock mddev and return before invoking raid5_quiesce() when conf is     NULL, following the existing pattern in raid5_change_consistency_policy(). (CVE-2025-71135)
