Affected Products:	SUSE Linux Enterprise High Performance Computing 12 SP5 SUSE Linux Enterprise Server 12 SP5 SUSE Linux Enterprise Server for SAP Applications 12 SP5

An update that solves 12 vulnerabilities and has 38 security fixes can now be installed.

Description:

The SUSE Linux Enterprise 12 SP5 Azure 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-2021-3491: 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)
• 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)
