description: |
  This kernel-linus update is based on upstream 5.10.43 and fixes atleast
  the following security issues:

  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. 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 kernel ath10k driver. The Wi-Fi
  implementation does not verify the Message Integrity Check (authenticity)
  of fragmented TKIP frames. An adversary can abuse this to inject and
  possibly decrypt packets in WPA or WPA2 networks that support the TKIP
  data-confidentiality protocol (CVE-2020-26141). 
  
  An issue was discovered in the kernel ath10k driver. The WEP, WPA, WPA2,
  and WPA3 implementations accept second (or subsequent) broadcast fragments
  even when sent in plaintext and process them as full unfragmented frames.
  An adversary can abuse this to inject arbitrary network packets independent
  of the network configuration (CVE-2020-26145).

  An issue was discovered in the Linux kernel 5.8.9. The WEP, WPA, WPA2, and
  WPA3 implementations reassemble fragments even though some of them were
  sent in plaintext. This vulnerability can be abused to inject packets and/
  or exfiltrate selected fragments when another device sends fragmented
  frames and the WEP, CCMP, or GCMP data-confidentiality protocol is used
  (CVE-2020-26147).

  A double-free memory corruption in the Linux kernel HCI device
  initialization subsystem was found in the way user attach malicious HCI
  TTY Bluetooth device. A local user could use this flaw to crash the system
  (CVE-2021-3564).

  A use after free vulnerability has been found in the hci_sock_bound_ioctl()
  function of the Linux kernel. It can allow attackers to corrupt kernel
  heaps (kmalloc-8k to be specific) and adopt further exploitations
  (CVE-2021-3573).

  There is a null pointer dereference in llcp_sock_getname in net/nfc/
  llcp_sock.c of the Linux kernel. An unprivileged user can trigger this bug
  and cause denial of service (CVE-2021-3587).

  There is a guest triggered use-after-free in Linux xen-netback. A malicious
  or buggy network PV frontend can force Linux netback to disable the
  interface and terminate the receive kernel thread associated with queue 0
  in response to the frontend sending a malformed packet. Such kernel thread
  termination will lead to a use-after-free in Linux netback when the backend
  is destroyed, as the kernel thread associated with queue 0 will have already
  exited and thus the call to kthread_stop will be performed against a stale
  pointer. A malicious or buggy frontend driver can trigger a dom0 crash.
  Privilege escalation and information leaks cannot be ruled out.
  (CVE-2021-28691 / XSA-374).
