The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-2843 advisory.

  - Use-after-free vulnerability in the Linux kernel exploitable by a local attacker due to reuse of a DCCP     socket with an attached dccps_hc_tx_ccid object as a listener after being released. Fixed in Ubuntu Linux     kernel 5.4.0-51.56, 5.3.0-68.63, 4.15.0-121.123, 4.4.0-193.224, 3.13.0.182.191 and 3.2.0-149.196.
    (CVE-2020-16119)

  - u'Specifically timed and handcrafted traffic can cause internal errors in a WLAN device that lead to     improper layer 2 Wi-Fi encryption with a consequent possibility of information disclosure over the air for     a discrete set of traffic' in Snapdragon Auto, Snapdragon Compute, Snapdragon Connectivity, Snapdragon     Consumer IOT, Snapdragon Industrial IOT, Snapdragon Mobile, Snapdragon Voice & Music, Snapdragon     Wearables, Snapdragon Wired Infrastructure and Networking in APQ8053, IPQ4019, IPQ8064, MSM8909W,     MSM8996AU, QCA9531, QCN5502, QCS405, SDX20, SM6150, SM7150 (CVE-2020-3702)

  - In unix_scm_to_skb of af_unix.c, there is a possible use after free bug due to a race condition. This     could lead to local escalation of privilege with System execution privileges needed. User interaction is     not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-196926917References:
    Upstream kernel (CVE-2021-0920)

  - A flaw was found in the Linux kernel. A corrupted timer tree caused the task wakeup to be missing in the     timerqueue_add function in lib/timerqueue.c. This flaw allows a local attacker with special user     privileges to cause a denial of service, slowing and eventually stopping the system while running OSP.
    (CVE-2021-20317)

  - An issue was discovered in Linux: KVM through Improper handling of VM_IO|VM_PFNMAP vmas in KVM can bypass     RO checks and can lead to pages being freed while still accessible by the VMM and guest. This allows users     with the ability to start and control a VM to read/write random pages of memory and can result in local     privilege escalation. (CVE-2021-22543)

  - An out-of-bounds memory write flaw was found in the Linux kernel's joystick devices subsystem in versions     before 5.9-rc1, in the way the user calls ioctl JSIOCSBTNMAP. This flaw allows a local user to crash the     system or possibly escalate their privileges on the system. The highest threat from this vulnerability is     to confidentiality, integrity, as well as system availability. (CVE-2021-3612)

  - A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when     processing the VMCB (virtual machine control block) provided by the L1 guest to spawn/handle a nested     guest (L2). Due to improper validation of the int_ctl field, this issue could allow a malicious L1 to     enable AVIC support (Advanced Virtual Interrupt Controller) for the L2 guest. As a result, the L2 guest     would be allowed to read/write physical pages of the host, resulting in a crash of the entire system, leak     of sensitive data or potential guest-to-host escape. This flaw affects Linux kernel versions prior to     5.14-rc7. (CVE-2021-3653)

  - A vulnerability was found in the Linux kernel in versions prior to v5.14-rc1. Missing size validations on     inbound SCTP packets may allow the kernel to read uninitialized memory. (CVE-2021-3655)

  - A lack of CPU resource in the Linux kernel tracing module functionality in versions prior to 5.14-rc3 was     found in the way user uses trace ring buffer in a specific way. Only privileged local users (with     CAP_SYS_ADMIN capability) could use this flaw to starve the resources causing denial of service.
    (CVE-2021-3679)

  - hso_free_net_device in drivers/net/usb/hso.c in the Linux kernel through 5.13.4 calls unregister_netdev     without checking for the NETREG_REGISTERED state, leading to a use-after-free and a double free.
    (CVE-2021-37159)

  - ** DISPUTED ** In drivers/char/virtio_console.c in the Linux kernel before 5.13.4, data corruption or loss     can be triggered by an untrusted device that supplies a buf->len value exceeding the buffer size. NOTE:
    the vendor indicates that the cited data corruption is not a vulnerability in any existing use case; the     length validation was added solely for robustness in the face of anomalous host OS behavior.
    (CVE-2021-38160)

  - arch/x86/kvm/mmu/paging_tmpl.h in the Linux kernel before 5.12.11 incorrectly computes the access     permissions of a shadow page, leading to a missing guest protection page fault. (CVE-2021-38198)

  - fs/nfs/nfs4client.c in the Linux kernel before 5.13.4 has incorrect connection-setup ordering, which     allows operators of remote NFSv4 servers to cause a denial of service (hanging of mounts) by arranging for     those servers to be unreachable during trunking detection. (CVE-2021-38199)

  - inflect is vulnerable to Inefficient Regular Expression Complexity (CVE-2021-3820)

  - drivers/usb/host/max3421-hcd.c in the Linux kernel before 5.13.6 allows physically proximate attackers to     cause a denial of service (use-after-free and panic) by removing a MAX-3421 USB device in certain     situations. (CVE-2021-38204)

  - drivers/net/ethernet/xilinx/xilinx_emaclite.c in the Linux kernel before 5.13.3 makes it easier for     attackers to defeat an ASLR protection mechanism because it prints a kernel pointer (i.e., the real IOMEM     pointer). (CVE-2021-38205)

  - A race condition was discovered in ext4_write_inline_data_end in fs/ext4/inline.c in the ext4 subsystem in     the Linux kernel through 5.13.13. (CVE-2021-40490)

  - prealloc_elems_and_freelist in kernel/bpf/stackmap.c in the Linux kernel through 5.14.9 allows     unprivileged users to trigger an eBPF multiplication integer overflow with a resultant out-of-bounds     write. (CVE-2021-41864)

  - The decode_data function in drivers/net/hamradio/6pack.c in the Linux kernel before 5.13.13 has a slab     out-of-bounds write. Input from a process that has the CAP_NET_ADMIN capability can lead to root access.
    (CVE-2021-42008)

  - The firewire subsystem in the Linux kernel through 5.14.13 has a buffer overflow related to     drivers/media/firewire/firedtv-avc.c and drivers/media/firewire/firedtv-ci.c, because avc_ca_pmt     mishandles bounds checking. (CVE-2021-42739)

  - An issue was discovered in the Linux kernel before 5.14.15. There is an array-index-out-of-bounds flaw in     the detach_capi_ctr function in drivers/isdn/capi/kcapi.c. (CVE-2021-43389)
