drivers/net/ethernet/xilinx/ll_temac_main.c in the Linux kernel before 5.12.13 allows remote attackers to cause a denial of service (buffer overflow and lockup) by sending heavy network traffic for about ten minutes.

According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - In the Linux kernel through 5.13.7, an unprivileged BPF program can obtain sensitive information from     kernel memory via a Speculative Store Bypass side-channel attack because the protection mechanism neglects     the possibility of uninitialized memory locations on the BPF stack. (CVE-2021-34556)

  - In the Linux kernel through 5.13.7, an unprivileged BPF program can obtain sensitive information from     kernel memory via a Speculative Store Bypass side-channel attack because a certain preempting store     operation does not necessarily occur before a store operation that has an attacker-controlled value.
    (CVE-2021-35477)

  - 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)

  - 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)

  - 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)

  - drivers/net/ethernet/xilinx/ll_temac_main.c in the Linux kernel before 5.12.13 allows remote attackers to     cause a denial of service (buffer overflow and lockup) by sending heavy network traffic for about ten     minutes. (CVE-2021-38207)

  - net/nfc/llcp_sock.c in the Linux kernel before 5.12.10 allows local unprivileged users to cause a denial     of service (NULL pointer dereference and BUG) by making a getsockname call after a certain type of failure     of a bind call. (CVE-2021-38208)

The remote Ubuntu 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5120-1 advisory.

  - In the Linux kernel 5.0.21, mounting a crafted f2fs filesystem image can lead to slab-out-of-bounds read     access in f2fs_build_segment_manager in fs/f2fs/segment.c, related to init_min_max_mtime in     fs/f2fs/segment.c (because the second argument to get_seg_entry is not validated). (CVE-2019-19449)

  - The Linux kernel through 5.8.13 does not properly enforce the Secure Boot Forbidden Signature Database     (aka dbx) protection mechanism. This affects certs/blacklist.c and certs/system_keyring.c.
    (CVE-2020-26541)

  - An issue was discovered in the Linux kernel before 5.9. arch/x86/kvm/svm/sev.c allows attackers to cause a     denial of service (soft lockup) by triggering destruction of a large SEV VM (which requires unregistering     many encrypted regions), aka CID-7be74942f184. (CVE-2020-36311)

  - 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 memory overflow vulnerability was found in the Linux kernel's ipc functionality of the memcg subsystem,     in the way a user calls the semget function multiple times, creating semaphores. This flaw allows a local     user to starve the resources, causing a denial of service. The highest threat from this vulnerability is     to system availability. (CVE-2021-3759)

  - 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)
