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:

    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)

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

    swiotlb: fix info leak with DMA_FROM_DEVICE (CVE-2022-48853)

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

    dm integrity: fix memory corruption when tag_size is less than digest size (CVE-2022-49044)

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

    scsi: target: tcmu: Fix possible page UAF (CVE-2022-49053)

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

    mmmremap.c: avoid pointless invalidate_range_start/end on mremap(old_size=0) (CVE-2022-49077)

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

    lz4: fix LZ4_decompress_safe_partial read out of bound (CVE-2022-49078)

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

    mm/mempolicy: fix mpol_new leak in shared_policy_replace (CVE-2022-49080)

    qede: confirm skb is allocated before using (CVE-2022-49084)

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

    rxrpc: fix a race in rxrpc_exit_net() (CVE-2022-49087)

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

    Drivers: hv: vmbus: Fix potential crash on module unload (CVE-2022-49098)

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

    ACPI: CPPC: Avoid out of bounds access when parsing _CPC data (CVE-2022-49145)

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

    scsi: qla2xxx: Suppress a kernel complaint in qla_create_qpair() (CVE-2022-49155)

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

    ntfs: add sanity check on allocation size (CVE-2022-49166)

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

    ext4: don't BUG if someone dirty pages without asking ext4 first (CVE-2022-49171)

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

    bfq: fix use-after-free in bfq_dispatch_request (CVE-2022-49176)

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

    block, bfq: don't move oom_bfqq (CVE-2022-49179)

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

    LSM: general protection fault in legacy_parse_param (CVE-2022-49180)

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

    bpf, sockmap: Fix more uncharged while msg has more_data (CVE-2022-49204)

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

    RDMA/mlx5: Fix memory leak in error flow for subscribe event routine (CVE-2022-49206)

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

    bpf, sockmap: Fix memleak in tcp_bpf_sendmsg while sk msg is full (CVE-2022-49209)

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

    NFSD: prevent integer overflow on 32 bit systems (CVE-2022-49279)

    A flaw that boot CPU could be vulnerable for the speculative execution behavior kind of attacks in the     Linux kernel X86 CPU Power management options functionality was found in the way user resuming CPU from     suspend-to-RAM. A local user could use this flaw to potentially get unauthorized access to some memory of     the CPU similar to the speculative execution behavior kind of attacks. (CVE-2023-1637)
