The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:2321-1 advisory.

  - An issue was discovered in the Linux kernel before 5.0.19. The XFRM subsystem has a use-after-free,     related to an xfrm_state_fini panic, aka CID-dbb2483b2a46. (CVE-2019-25045)

  - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent     Privacy (WEP) doesn't require that the A-MSDU flag in the plaintext QoS header field is authenticated.
    Against devices that support receiving non-SSP A-MSDU frames (which is mandatory as part of 802.11n), an     adversary can abuse this to inject arbitrary network packets. (CVE-2020-24588)

  - Bluetooth LE and BR/EDR secure pairing in Bluetooth Core Specification 2.1 through 5.2 may permit a nearby     man-in-the-middle attacker to identify the Passkey used during pairing (in the Passkey authentication     procedure) by reflection of the public key and the authentication evidence of the initiating device,     potentially permitting this attacker to complete authenticated pairing with the responding device using     the correct Passkey for the pairing session. The attack methodology determines the Passkey value one bit     at a time. (CVE-2020-26558)

  - An issue was discovered in the Linux kernel before 5.8.1. net/bluetooth/hci_event.c has a slab out-of-     bounds read in hci_extended_inquiry_result_evt, aka CID-51c19bf3d5cf. (CVE-2020-36386)

  - Improper access control in BlueZ may allow an authenticated user to potentially enable information     disclosure via adjacent access. (CVE-2021-0129)

  - In __hidinput_change_resolution_multipliers of hid-input.c, there is a possible out of bounds write due to     a heap buffer overflow. This could lead to local escalation of privilege with no additional execution     privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android     kernelAndroid ID: A-173843328References: Upstream kernel (CVE-2021-0512)

  - In pfkey_dump of af_key.c, there is a possible out-of-bounds read due to a missing bounds check. This     could lead to local information disclosure in the kernel with System execution privileges needed. User     interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-110373476     (CVE-2021-0605)

  - In kernel/bpf/verifier.c in the Linux kernel before 5.12.13, a branch can be mispredicted (e.g., because     of type confusion) and consequently an unprivileged BPF program can read arbitrary memory locations via a     side-channel attack, aka CID-9183671af6db. (CVE-2021-33624)

  - net/can/bcm.c in the Linux kernel through 5.12.10 allows local users to obtain sensitive information from     kernel stack memory because parts of a data structure are uninitialized. (CVE-2021-34693)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

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

  - An issue was discovered in the Linux kernel before 5.0.19. The XFRM subsystem has a use-after-free,     related to an xfrm_state_fini panic, aka CID-dbb2483b2a46. (CVE-2019-25045)

  - An issue was discovered in the Linux kernel before 5.10. drivers/infiniband/core/ucma.c has a use-after-     free because the ctx is reached via the ctx_list in some ucma_migrate_id situations where ucma_close is     called, aka CID-f5449e74802c. (CVE-2020-36385)

  - In ep_loop_check_proc of eventpoll.c, there is a possible way to corrupt memory due to a use after free.
    This could lead to local escalation of privilege with no additional execution privileges needed. User     interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID:
    A-204573007References: Upstream kernel (CVE-2021-1048)

  - An information disclosure vulnerability exists in the ARM SIGPAGE functionality of Linux Kernel v5.4.66     and v5.4.54. The latest version (5.11-rc4) seems to still be vulnerable. A userland application can read     the contents of the sigpage, which can leak kernel memory contents. An attacker can read a process's     memory at a specific offset to trigger this vulnerability. This was fixed in kernel releases: 4.14.222     4.19.177 5.4.99 5.10.17 5.11 (CVE-2021-21781)

  - A heap out-of-bounds write affecting Linux since v2.6.19-rc1 was discovered in net/netfilter/x_tables.c.
    This allows an attacker to gain privileges or cause a DoS (via heap memory corruption) through user name     space (CVE-2021-22555)

  - In kernel/bpf/verifier.c in the Linux kernel before 5.12.13, a branch can be mispredicted (e.g., because     of type confusion) and consequently an unprivileged BPF program can read arbitrary memory locations via a     side-channel attack, aka CID-9183671af6db. (CVE-2021-33624)

  - fs/seq_file.c in the Linux kernel 3.16 through 5.13.x before 5.13.4 does not properly restrict seq buffer     allocations, leading to an integer overflow, an Out-of-bounds Write, and escalation to root by an     unprivileged user, aka CID-8cae8cd89f05. (CVE-2021-33909)

  - net/can/bcm.c in the Linux kernel through 5.12.10 allows local users to obtain sensitive information from     kernel stack memory because parts of a data structure are uninitialized. (CVE-2021-34693)

  - 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)

  - arch/powerpc/kvm/book3s_rtas.c in the Linux kernel through 5.13.5 on the powerpc platform allows KVM guest     OS users to cause host OS memory corruption via rtas_args.nargs, aka CID-f62f3c20647e. (CVE-2021-37576)

  - ** 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)

  - net/netfilter/nf_conntrack_standalone.c in the Linux kernel before 5.12.2 allows observation of changes in     any net namespace because these changes are leaked into all other net namespaces. This is related to the     NF_SYSCTL_CT_MAX, NF_SYSCTL_CT_EXPECT_MAX, and NF_SYSCTL_CT_BUCKETS sysctls. (CVE-2021-38209)

  - 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)

User     interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-110373476     (CVE-2021-0605)

  - An information disclosure vulnerability exists in the ARM SIGPAGE functionality of Linux Kernel v5.4.66     and v5.4.54. The latest version (5.11-rc4) seems to still be vulnerable. A userland application can read     the contents of the sigpage, which can leak kernel memory contents. An attacker can read a process's     memory at a specific offset to trigger this vulnerability. This was fixed in kernel releases: 4.14.222     4.19.177 5.4.99 5.10.17 5.11 (CVE-2021-21781)

  - A heap out-of-bounds write affecting Linux since v2.6.19-rc1 was discovered in net/netfilter/x_tables.c.
    This allows an attacker to gain privileges or cause a DoS (via heap memory corruption) through user name     space (CVE-2021-22555)

  - An issue was discovered in the Linux kernel through 5.11.x. kernel/bpf/verifier.c performs undesirable     out-of-bounds speculation on pointer arithmetic, leading to side-channel attacks that defeat Spectre     mitigations and obtain sensitive information from kernel memory. Specifically, for sequences of pointer     arithmetic operations, the pointer modification performed by the first operation is not correctly     accounted for when restricting subsequent operations. (CVE-2021-29155)

  - kernel/bpf/verifier.c in the Linux kernel through 5.12.1 performs undesirable speculative loads, leading     to disclosure of stack content via side-channel attacks, aka CID-801c6058d14a. The specific concern is not     protecting the BPF stack area against speculative loads. Also, the BPF stack can contain uninitialized     data that might represent sensitive information previously operated on by the kernel. (CVE-2021-31829)

  - An out-of-bounds (OOB) memory write flaw was found in list_devices in drivers/md/dm-ioctl.c in the Multi-     device driver module in the Linux kernel before 5.12. A bound check failure allows an attacker with     special user (CAP_SYS_ADMIN) privilege to gain access to out-of-bounds memory leading to a system crash or     a leak of internal kernel information. The highest threat from this vulnerability is to system     availability. (CVE-2021-31916)

  - The Linux kernel before 5.11.14 has a use-after-free in cipso_v4_genopt in net/ipv4/cipso_ipv4.c because     the CIPSO and CALIPSO refcounting for the DOI definitions is mishandled, aka CID-ad5d07f4a9cd. This leads     to writing an arbitrary value. (CVE-2021-33033)

  - kernel/bpf/verifier.c in the Linux kernel through 5.12.7 enforces incorrect limits for pointer arithmetic     operations, aka CID-bb01a1bba579. This can be abused to perform out-of-bounds reads and writes in kernel     memory, leading to local privilege escalation to root. In particular, there is a corner case where the off     reg causes a masking direction change, which then results in an incorrect final aux->alu_limit.
    (CVE-2021-33200)

  - In kernel/bpf/verifier.c in the Linux kernel before 5.12.13, a branch can be mispredicted (e.g., because     of type confusion) and consequently an unprivileged BPF program can read arbitrary memory locations via a     side-channel attack, aka CID-9183671af6db. (CVE-2021-33624)

  - fs/seq_file.c in the Linux kernel 3.16 through 5.13.x before 5.13.4 does not properly restrict seq buffer     allocations, leading to an integer overflow, an Out-of-bounds Write, and escalation to root by an     unprivileged user, aka CID-8cae8cd89f05. (CVE-2021-33909)

  - The bpf verifier in the Linux kernel did not properly handle mod32 destination register truncation when     the source register was known to be 0. A local attacker with the ability to load bpf programs could use     this gain out-of-bounds reads in kernel memory leading to information disclosure (kernel memory), and     possibly out-of-bounds writes that could potentially lead to code execution. This issue was addressed in     the upstream kernel in commit 9b00f1b78809 ('bpf: Fix truncation handling for mod32 dst reg wrt zero') and     in Linux stable kernels 5.11.2, 5.10.19, and 5.4.101. (CVE-2021-3444)

  - net/can/bcm.c in the Linux kernel through 5.12.10 allows local users to obtain sensitive information from     kernel stack memory because parts of a data structure are uninitialized. (CVE-2021-34693)

  - 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)

  - arch/powerpc/kvm/book3s_rtas.c in the Linux kernel through 5.13.5 on the powerpc platform allows KVM guest     OS users to cause host OS memory corruption via rtas_args.nargs, aka CID-f62f3c20647e. (CVE-2021-37576)

  - ** 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)

The remote SUSE Linux SLES12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:2349-1 advisory.

  - An issue was discovered in the Linux kernel before 5.0.19. The XFRM subsystem has a use-after-free,     related to an xfrm_state_fini panic, aka CID-dbb2483b2a46. (CVE-2019-25045)

  - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent     Privacy (WEP) doesn't require that the A-MSDU flag in the plaintext QoS header field is authenticated.
    Against devices that support receiving non-SSP A-MSDU frames (which is mandatory as part of 802.11n), an     adversary can abuse this to inject arbitrary network packets. (CVE-2020-24588)

  - Bluetooth LE and BR/EDR secure pairing in Bluetooth Core Specification 2.1 through 5.2 may permit a nearby     man-in-the-middle attacker to identify the Passkey used during pairing (in the Passkey authentication     procedure) by reflection of the public key and the authentication evidence of the initiating device,     potentially permitting this attacker to complete authenticated pairing with the responding device using     the correct Passkey for the pairing session. The attack methodology determines the Passkey value one bit     at a time. (CVE-2020-26558)

  - An issue was discovered in the Linux kernel before 5.8.1. net/bluetooth/hci_event.c has a slab out-of-     bounds read in hci_extended_inquiry_result_evt, aka CID-51c19bf3d5cf. (CVE-2020-36386)

  - Improper access control in BlueZ may allow an authenticated user to potentially enable information     disclosure via adjacent access. (CVE-2021-0129)

  - In __hidinput_change_resolution_multipliers of hid-input.c, there is a possible out of bounds write due to     a heap buffer overflow.
