"The remote SUSE Linux SLES11 / SLES_SAP11 host has packages installed that are affected by multiple vulnerabilities as
referenced in the SUSE-SU-2021:14764-1 advisory.

  - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent
    Privacy (WEP) doesn't require that received fragments be cleared from memory after (re)connecting to a
    network. Under the right circumstances, when another device sends fragmented frames encrypted using WEP,
    CCMP, or GCMP, this can be abused to inject arbitrary network packets and/or exfiltrate user data.
    (CVE-2020-24586)

  - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent
    Privacy (WEP) doesn't require that all fragments of a frame are encrypted under the same key. An adversary
    can abuse this to decrypt selected fragments when another device sends fragmented frames and the WEP,
    CCMP, or GCMP encryption key is periodically renewed. (CVE-2020-24587)

  - 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)

  - An issue was discovered in the kernel in NetBSD 7.1. An Access Point (AP) forwards EAPOL frames to other
    clients even though the sender has not yet successfully authenticated to the AP. This might be abused in
    projected Wi-Fi networks to launch denial-of-service attacks against connected clients and makes it easier
    to exploit other vulnerabilities in connected clients. (CVE-2020-26139)

  - 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)

  - 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)

  - BPF JIT compilers in the Linux kernel through 5.11.12 have incorrect computation of branch displacements,
    allowing them to execute arbitrary code within the kernel context. This affects
    arch/x86/net/bpf_jit_comp.c and arch/x86/net/bpf_jit_comp32.c. (CVE-2021-29154)

  - net/bluetooth/hci_request.c in the Linux kernel through 5.12.2 has a race condition for removal of the HCI
    controller. (CVE-2021-32399)

  - 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)
