    Description

      The SUSE Linux Enterprise 15 SP1 kernel was updated to receive various
      security and bugfixes.

      The following security bugs were fixed:

      • CVE-2021-33200: Enforcing incorrect limits for pointer arithmetic
        operations by the BPF verifier could be abused to perform out-of-bounds
        reads and writes in kernel memory (bsc#1186484).
      • CVE-2021-33034: Fixed a use-after-free when destroying an hci_chan. This
        could lead to writing an arbitrary values. (bsc#1186111)
      • CVE-2020-26139: Fixed a denial-of-service when an Access Point (AP)
        forwards EAPOL frames to other clients even though the sender has not
        yet successfully authenticated to the AP. (bnc#1186062)
      • CVE-2021-23134: A Use After Free vulnerability in nfc sockets allowed
        local attackers to elevate their privileges. (bnc#1186060)
      • CVE-2021-23133: Fixed a race condition in SCTP sockets, which could lead
        to privilege escalation from the context of a network service or an
        unprivileged process. (bnc#1184675)
      • CVE-2021-3491: Fixed a potential heap overflow in mem_rw(). This
        vulnerability is related to the PROVIDE_BUFFERS operation, which allowed
        the MAX_RW_COUNT limit to be bypassed (bsc#1185642).
      • CVE-2021-32399: Fixed a race condition when removing the HCI controller
        (bnc#1184611).
      • 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 received fragments be cleared from memory after
        (re)connecting to a network. Under the right circumstances this can be
        abused to inject arbitrary network packets and/or exfiltrate user data
        (bnc#1185859).
      • 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 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 (bnc#1185859 bnc#1185862).
      • CVE-2020-26147: 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 (bnc#1185859).
      • CVE-2020-26145: An issue was discovered with Samsung Galaxy S3 i9305
        4.4.4 devices. 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. (bnc#1185860)
      • CVE-2020-26141: An issue was discovered in the ALFA driver for AWUS036H,
        where the Message Integrity Check (authenticity) of fragmented TKIP
        frames was not verified. An adversary can abuse this to inject and
        possibly decrypt packets in WPA or WPA2 networks that support the TKIP
        data-confidentiality protocol. (bnc#1185987)
