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

  - An issue was discovered in the Linux kernel through 5.10.1, as used with Xen through 4.14.x. The Linux     kernel PV block backend expects the kernel thread handler to reset ring->xenblkd to NULL when stopped.
    However, the handler may not have time to run if the frontend quickly toggles between the states connect     and disconnect. As a consequence, the block backend may re-use a pointer after it was freed. A misbehaving     guest can trigger a dom0 crash by continuously connecting / disconnecting a block frontend. Privilege     escalation and information leaks cannot be ruled out. This only affects systems with a Linux blkback.
    (CVE-2020-29569)

  - Rogue backends can cause DoS of guests via high frequency events T[his CNA information record relates to     multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Xen offers the     ability to run PV backends in regular unprivileged guests, typically referred to as 'driver domains'.
    Running PV backends in driver domains has one primary security advantage: if a driver domain gets     compromised, it doesn't have the privileges to take over the system. However, a malicious driver domain     could try to attack other guests via sending events at a high frequency leading to a Denial of Service in     the guest due to trying to service interrupts for elongated amounts of time. There are three affected     backends: * blkfront patch 1, CVE-2021-28711 * netfront patch 2, CVE-2021-28712 * hvc_xen (console) patch     3, CVE-2021-28713 (CVE-2021-28711, CVE-2021-28712, CVE-2021-28713)

  - Improper input validation in the Intel(R) Ethernet ixgbe driver for Linux before version 3.17.3 may allow     an authenticated user to potentially enable denial of service via local access. (CVE-2021-33098)

  - In gre_handle_offloads of ip_gre.c, there is a possible page fault due to an invalid memory access. This     could lead to local information disclosure with no additional execution privileges needed. User     interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID:
    A-150694665References: Upstream kernel (CVE-2021-39633)

  - In various setup methods of the USB gadget subsystem, there is a possible out of bounds write due to an     incorrect flag check.

User interaction is not needed for exploitation.Product: AndroidVersions: Android     kernelAndroid ID: A-210292376References: Upstream kernel (CVE-2021-39685)

  - An unprivileged write to the file handler flaw in the Linux kernel's control groups and namespaces     subsystem was found in the way users have access to some less privileged process that are controlled by     cgroups and have higher privileged parent process. It is actually both for cgroup2 and cgroup1 versions of     control groups. A local user could use this flaw to crash the system or escalate their privileges on the     system. (CVE-2021-4197)

  - A use-after-free read flaw was found in sock_getsockopt() in net/core/sock.c due to SO_PEERCRED and     SO_PEERGROUPS race with listen() (and connect()) in the Linux kernel. In this flaw, an attacker with a     user privileges may crash the system or leak internal kernel information. (CVE-2021-4203)

  - A use-after-free exists in drivers/tee/tee_shm.c in the TEE subsystem in the Linux kernel through 5.15.11.
    This occurs because of a race condition in tee_shm_get_from_id during an attempt to free a shared memory     object. (CVE-2021-44733)

  - In the IPv6 implementation in the Linux kernel before 5.13.3, net/ipv6/output_core.c has an information     leak because of certain use of a hash table which, although big, doesn't properly consider that IPv6-based     attackers can typically choose among many IPv6 source addresses. (CVE-2021-45485)

  - A flaw was found in the sctp_make_strreset_req function in net/sctp/sm_make_chunk.c in the SCTP network     protocol in the Linux kernel with a local user privilege access. In this flaw, an attempt to use more     buffer than is allocated triggers a BUG_ON issue, leading to a denial of service (DOS). (CVE-2022-0322)

  - Guest can force Linux netback driver to hog large amounts of kernel memory T[his CNA information record     relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.]     Incoming data packets for a guest in the Linux kernel's netback driver are buffered until the guest is     ready to process them. There are some measures taken for avoiding to pile up too much data, but those can     be bypassed by the guest: There is a timeout how long the client side of an interface can stop consuming     new packets before it is assumed to have stalled, but this timeout is rather long (60 seconds by default).
    Using a UDP connection on a fast interface can easily accumulate gigabytes of data in that time.
    (CVE-2021-28715) The timeout could even never trigger if the guest manages to have only one free slot in     its RX queue ring page and the next package would require more than one free slot, which may be the case     when using GSO, XDP, or software hashing.

The remote SUSE Linux SLES15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:0288-1 advisory.

  - A read-after-free memory flaw was found in the Linux kernel's garbage collection for Unix domain socket     file handlers in the way users call close() and fget() simultaneously and can potentially trigger a race     condition. This flaw allows a local user to crash the system or escalate their privileges on the system.
    This flaw affects Linux kernel versions prior to 5.16-rc4. (CVE-2021-4083)

  - A memory leak vulnerability was found in the Linux kernel's eBPF for the Simulated networking device     driver in the way user uses BPF for the device such that function nsim_map_alloc_elem being called.

  - A vulnerability was found in btrfs_alloc_tree_b in fs/btrfs/extent-tree.c in the Linux kernel due to an     improper lock operation in btrfs. In this flaw, a user with a local privilege may cause a denial of     service (DOS) due to a deadlock problem. (CVE-2021-4149)

  - An unprivileged write to the file handler flaw in the Linux kernel's control groups and namespaces     subsystem was found in the way users have access to some less privileged process that are controlled by     cgroups and have higher privileged parent process. It is actually both for cgroup2 and cgroup1 versions of     control groups. A local user could use this flaw to crash the system or escalate their privileges on the     system. (CVE-2021-4197)

  - A use-after-free flaw was found in nci_request in net/nfc/nci/core.c in NFC Controller Interface (NCI) in     the Linux kernel. This flaw could allow a local attacker with user privileges to cause a data race problem     while the device is getting removed, leading to a privilege escalation problem. (CVE-2021-4202)

  - A use-after-free exists in drivers/tee/tee_shm.c in the TEE subsystem in the Linux kernel through 5.15.11.
    This occurs because of a race condition in tee_shm_get_from_id during an attempt to free a shared memory     object. (CVE-2021-44733)

  - nf_tables_newset in net/netfilter/nf_tables_api.c in the Linux kernel before 5.12.13 allows local users to     cause a denial of service (NULL pointer dereference and general protection fault) because of the missing     initialization for nft_set_elem_expr_alloc.

  - A read-after-free memory flaw was found in the Linux kernel's garbage collection for Unix domain socket     file handlers in the way users call close() and fget() simultaneously and can potentially trigger a race     condition. This flaw allows a local user to crash the system or escalate their privileges on the system.
    This flaw affects Linux kernel versions prior to 5.16-rc4. (CVE-2021-4083)

  - A memory leak vulnerability was found in the Linux kernel's eBPF for the Simulated networking device     driver in the way user uses BPF for the device such that function nsim_map_alloc_elem being called. A     local user could use this flaw to get unauthorized access to some data. (CVE-2021-4135)

  - An unprivileged write to the file handler flaw in the Linux kernel's control groups and namespaces     subsystem was found in the way users have access to some less privileged process that are controlled by     cgroups and have higher privileged parent process. It is actually both for cgroup2 and cgroup1 versions of     control groups. A local user could use this flaw to crash the system or escalate their privileges on the     system. (CVE-2021-4197)

  - A use-after-free flaw was found in nci_request in net/nfc/nci/core.c in NFC Controller Interface (NCI) in     the Linux kernel. This flaw could allow a local attacker with user privileges to cause a data race problem     while the device is getting removed, leading to a privilege escalation problem. (CVE-2021-4202)

  - A use-after-free exists in drivers/tee/tee_shm.c in the TEE subsystem in the Linux kernel through 5.15.11.
    This occurs because of a race condition in tee_shm_get_from_id during an attempt to free a shared memory     object. (CVE-2021-44733)

  - A flaw was found in the sctp_make_strreset_req function in net/sctp/sm_make_chunk.c in the SCTP network     protocol in the Linux kernel with a local user privilege access. In this flaw, an attempt to use more     buffer than is allocated triggers a BUG_ON issue, leading to a denial of service (DOS). (CVE-2022-0322)

  - A random memory access flaw was found in the Linux kernel's GPU i915 kernel driver functionality in the     way a user may run malicious code on the GPU. This flaw allows a local user to crash the system or     escalate their privileges on the system. (CVE-2022-0330)

  - A stack overflow flaw was found in the Linux kernel's TIPC protocol functionality in the way a user sends     a packet with malicious content where the number of domain member nodes is higher than the 64 allowed.
    This flaw allows a remote user to crash the system or possibly escalate their privileges if they have     access to the TIPC network. (CVE-2022-0435)

  - kernel: failing usercopy allows for use-after-free exploitation (CVE-2022-22942)
