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: ALSA: pcm: Fix potential AB/BA lock     with buffer_mutex and mmap_lock syzbot caught a potential deadlock between the PCM runtime->buffer_mutex     and the mm->mmap_lock. It was brought by the recent fix to cover the racy read/write and other ioctls, and     in that commit, I overlooked a (hopefully only) corner case that may take the revert lock, namely, the OSS     mmap. The OSS mmap operation exceptionally allows to re-configure the parameters inside the OSS mmap     syscall, where mm->mmap_mutex is already held. Meanwhile, the copy_from/to_user calls at read/write     operations also take the mm->mmap_lock internally, hence it may lead to a AB/BA deadlock. A similar     problem was already seen in the past and we fixed it with a refcount (in commit b248371628aa). The former     fix covered only the call paths with OSS read/write and OSS ioctls, while we need to cover the concurrent     access via both ALSA and OSS APIs now. This patch addresses the problem above by replacing the     buffer_mutex lock in the read/write operations with a refcount similar as we've used for OSS. The new     field, runtime->buffer_accessing, keeps the number of concurrent read/write operations. Unlike the former     buffer_mutex protection, this protects only around the copy_from/to_user() calls; the other codes are     basically protected by the PCM stream lock. The refcount can be a negative, meaning blocked by the ioctls.
    If a negative value is seen, the read/write aborts with -EBUSY. In the ioctl side, OTOH, they check this     refcount, too, and set to a negative value for blocking unless it's already being accessed.
    (CVE-2022-49272)

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

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 Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-989111 advisory.

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

    ALSA: pcm: Fix potential AB/BA lock with buffer_mutex and mmap_lock

    syzbot caught a potential deadlock between the PCM     runtime->buffer_mutex and the mm->mmap_lock.  It was brought by the     recent fix to cover the racy read/write and other ioctls, and in that     commit, I overlooked a (hopefully only) corner case that may take the     revert lock, namely, the OSS mmap.  The OSS mmap operation     exceptionally allows to re-configure the parameters inside the OSS     mmap syscall, where mm->mmap_mutex is already held.  Meanwhile, the     copy_from/to_user calls at read/write operations also take the     mm->mmap_lock internally, hence it may lead to a AB/BA deadlock.

    A similar problem was already seen in the past and we fixed it with a     refcount (in commit b248371628aa).  The former fix covered only the     call paths with OSS read/write and OSS ioctls, while we need to cover     the concurrent access via both ALSA and OSS APIs now.

    This patch addresses the problem above by replacing the buffer_mutex     lock in the read/write operations with a refcount similar as we've     used for OSS.  The new field, runtime->buffer_accessing, keeps the     number of concurrent read/write operations.  Unlike the former     buffer_mutex protection, this protects only around the     copy_from/to_user() calls; the other codes are basically protected by     the PCM stream lock.  The refcount can be a negative, meaning blocked     by the ioctls.  If a negative value is seen, the read/write aborts     with -EBUSY.  In the ioctl side, OTOH, they check this refcount, too,     and set to a negative value for blocking unless it's already being     accessed.
