The remote SUSE Linux SLES12 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2025:02087-1 advisory.

    This update for the Linux Kernel 4.12.14-122_244 fixes several issues.

    The following security issues were fixed:

    - CVE-2024-56601: net: inet: do not leave a dangling sk pointer in inet_create() (bsc#1235231).
    - CVE-2022-49545: ALSA: usb-audio: Cancel pending work at closing a MIDI substream (bsc#1238730).
    - CVE-2022-49179: block, bfq: do not move oom_bfqq (bsc#1241331).

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.

The version of kernel installed on the remote host is prior to 5.10.112-108.499. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.10-2023-036 advisory.

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

    ubi: Fix race condition between ctrl_cdev_ioctl and ubi_cdev_ioctl (CVE-2021-47634)

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

    Revert Revert block, bfq: honor already-setup queue merges (CVE-2021-47646)

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

    ASoC: soc-compress: prevent the potentially use of null pointer (CVE-2021-47650)

    A denial of service (DOS) issue was found in the Linux kernel's smb2_ioctl_query_info function in     the fs/cifs/smb2ops.c Common Internet File System (CIFS) due to an incorrect return from the memdup_user     function. This flaw allows a local, privileged (CAP_SYS_ADMIN) attacker to crash the system.
    (CVE-2022-0168)

    When the KVM updates the guest's page table entry, it will first use get_user_pages_fast() to pin the     page, and when it fails (e.g. the vma->flags has VM_IO or VM_PFNMAP), it will get corresponding VMA where     the page lies in through find_vma_intersection(), calculate the physical address, and map the page to the     kernel virtual address through memremap(), and finally, write the update.The problem is that when we get     the vma through find_vma_intersection(), only VM_PFNMAP is checked, not both VM_IO and VM_PFNMAP. In the     reproducer below, after the KVM_SET_USER_MEMORY_REGION is completed, we replace the guest's memory mapping     with the kernel-user shared region of io_uring and then perform the KVM_TRANSLATE operation, which finally     triggers the page table entry update. Now, memremap() will return page_offset_base (direct mapping of all     physical memory) + vaddr (the linear address of KVM_TRANSLATE) + vm_pgoff (the offset when io_uring     performs mmap(2)), and use the return value as the base address for CMPXCHG (write 0x21 in this case).
    Since both vaddr and vm_pgoff are controllable by the user-mode process, writing may exceed the previously     mapped guest memory space and trigger exceptions such as UAF. The vulnerability shares similarities with     CVE-2021-22543. (CVE-2022-1158)

    A vulnerability was found in the pfkey_register function in net/key/af_key.c in the Linux kernel. This     flaw allows a local, unprivileged user to gain access to kernel memory, leading to a system crash or a     leak of internal kernel information. (CVE-2022-1353)

    A use-after-free flaw was found in the Linux kernel's io_uring interface subsystem in the way a user     triggers a race condition between timeout flush and removal. This flaw allows a local user to crash or     escalate their privileges on the system. (CVE-2022-29582)

    A flaw was found in the Linux kernel implementation of proxied virtualized TPM devices. On a system where     virtualized TPM devices are configured (this is not the default) a local attacker can create a use-after-     free and create a situation where it may be possible to escalate privileges on the system. (CVE-2022-2977)

    A flaw was found in the Linux kernel. A NULL pointer dereference may occur while a slip driver is in     progress to detach in sl_tx_timeout in drivers/net/slip/slip.c. This issue could allow an attacker to     crash the system or leak internal kernel information. (CVE-2022-41858)

The version of kernel installed on the remote host is prior to 5.4.190-107.353. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.4-2024-076 advisory.

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

    ubi: Fix race condition between ctrl_cdev_ioctl and ubi_cdev_ioctl (CVE-2021-47634)

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

    Revert Revert block, bfq: honor already-setup queue merges (CVE-2021-47646)

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

    ASoC: soc-compress: prevent the potentially use of null pointer (CVE-2021-47650)

    When the KVM updates the guest's page table entry, it will first use get_user_pages_fast() to pin the     page, and when it fails (e.g. the vma->flags has VM_IO or VM_PFNMAP), it will get corresponding VMA where     the page lies in through find_vma_intersection(), calculate the physical address, and map the page to the     kernel virtual address through memremap(), and finally, write the update.The problem is that when we get     the vma through find_vma_intersection(), only VM_PFNMAP is checked, not both VM_IO and VM_PFNMAP. In the     reproducer below, after the KVM_SET_USER_MEMORY_REGION is completed, we replace the guest's memory mapping     with the kernel-user shared region of io_uring and then perform the KVM_TRANSLATE operation, which finally     triggers the page table entry update. Now, memremap() will return page_offset_base (direct mapping of all     physical memory) + vaddr (the linear address of KVM_TRANSLATE) + vm_pgoff (the offset when io_uring     performs mmap(2)), and use the return value as the base address for CMPXCHG (write 0x21 in this case).
    Since both vaddr and vm_pgoff are controllable by the user-mode process, writing may exceed the previously     mapped guest memory space and trigger exceptions such as UAF. The vulnerability shares similarities with     CVE-2021-22543. (CVE-2022-1158)

    A vulnerability was found in the pfkey_register function in net/key/af_key.c in the Linux kernel. This     flaw allows a local, unprivileged user to gain access to kernel memory, leading to a system crash or a     leak of internal kernel information. (CVE-2022-1353)

    A flaw was found in the Linux kernel implementation of proxied virtualized TPM devices. On a system where     virtualized TPM devices are configured (this is not the default) a local attacker can create a use-after-     free and create a situation where it may be possible to escalate privileges on the system. (CVE-2022-2977)

    A flaw was found in the Linux kernel. A NULL pointer dereference may occur while a slip driver is in     progress to detach in sl_tx_timeout in drivers/net/slip/slip.c. This issue could allow an attacker to     crash the system or leak internal kernel information. (CVE-2022-41858)
