The SUSE Linux Enterprise 15 SP2 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-2020-24588: 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. (bnc#1185861) - 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) The following non-security bugs were fixed: - ACPI / hotplug / PCI: Fix reference count leak in enable_slot() (git-fixes). - ACPI: GTDT: Do not corrupt interrupt mappings on watchdow probe failure (git-fixes). - ACPI: custom_method: fix a possible memory leak (git-fixes). - ACPI: custom_method: fix potential use-after-free issue (git-fixes). - ALSA: bebob/oxfw: fix Kconfig entry for Mackie d.2 Pro (git-fixes). - ALSA: bebob: enable to deliver MIDI messages for multiple ports (git-fixes). - ALSA: dice: fix stream format at middle sampling rate for Alesis iO 26 (git-fixes). - ALSA: dice: fix stream format for TC Electronic Konnekt Live at high sampling transfer frequency (git-fixes). - ALSA: firewire-lib: fix calculation for size of IR context payload (git-fixes). - ALSA: firewire-lib: fix check for the size of isochronous packet payload (git-fixes). - ALSA: hda/conexant: Re-order CX5066 quirk table entries (git-fixes). - ALSA: hda/realtek: ALC285 Thinkpad jack pin quirk is unreachable (git-fixes). - ALSA: hda/realtek: Add some CLOVE SSIDs of ALC293 (git-fixes). - ALSA: hda/realtek: Headphone volume is controlled by Front mixer (git-fixes). - ALSA: hda/realtek: reset eapd coeff to default value for alc287 (git-fixes). - ALSA: hda: fixup headset for ASUS GU502 laptop (git-fixes). - ALSA: hda: generic: change the DAC ctl name for LO+SPK or LO+HP (git-fixes). - ALSA: hdsp: do not disable if not enabled (git-fixes). - ALSA: hdspm: do not disable if not enabled (git-fixes). - ALSA: intel8x0: Do not update period unless prepared (git-fixes). - ALSA: line6: Fix racy initialization of LINE6 MIDI (git-fixes). - ALSA: rme9652: do not disable if not enabled (git-fixes). - ALSA: usb-audio: Validate MS endpoint descriptors (git-fixes). - ALSA: usb-audio: fix control-request direction (git-fixes). - ALSA: usb-audio: scarlett2: Fix device hang with ehci-pci (git-fixes). - ALSA: usb-audio: scarlett2: Improve driver startup messages (git-fixes). - ALSA: usb-audio: scarlett2: snd_scarlett_gen2_controls_create() can be static (git-fixes). - ARM64: vdso32: Install vdso32 from vdso_install (git-fixes). - ASoC: Intel: bytcr_rt5640: Add quirk for the Chuwi Hi8 tablet (git-fixes). - ASoC: Intel: bytcr_rt5640: Enable jack-detect support on Asus T100TAF (git-fixes). - ASoC: cs35l33: fix an error code in probe() (git-fixes). - ASoC: cs42l42: Regmap must use_single_read/write (git-fixes). - ASoC: rsnd: call rsnd_ssi_master_clk_start() from rsnd_ssi_init() (git-fixes). - ASoC: rsnd: core: Check convert rate in rsnd_hw_params (git-fixes). - ASoC: rt286: Generalize support for ALC3263 codec (git-fixes). - ASoC: rt286: Make RT286_SET_GPIO_* readable and writable (git-fixes). - Bluetooth: L2CAP: Fix handling LE modes by L2CAP_OPTIONS (git-fixes). - Bluetooth: SMP: Fail if remote and local public keys are identical (git-fixes). - Bluetooth: Set CONF_NOT_COMPLETE as l2cap_chan default (git-fixes). - Bluetooth: check for zapped sk before connecting (git-fixes). - Bluetooth: initialize skb_queue_head at l2cap_chan_create() (git-fixes). - Drivers: hv: vmbus: Fix Suspend-to-Idle for Generation-2 VM (git-fixes). - Drivers: hv: vmbus: Increase wait time for VMbus unload (bsc#1185725). - Drivers: hv: vmbus: Initialize unload_event statically (bsc#1185725). - Drivers: hv: vmbus: Use after free in __vmbus_open() (git-fixes). - Input: elants_i2c - do not bind to i2c-hid compatible ACPI instantiated devices (git-fixes). - Input: silead - add workaround for x86 BIOS-es which bring the chip up in a stuck state (git-fixes). - KVM: s390: fix guarded storage control register handling (bsc#1133021). - Move upstreamed media fixes into sorted section - NFC: nci: fix memory leak in nci_allocate_device (git-fixes). - PCI/RCEC: Fix RCiEP device to RCEC association (git-fixes). - PCI: Allow VPD access for QLogic ISP2722 (git-fixes). - PCI: PM: Do not read power state in pci_enable_device_flags() (git-fixes). - PCI: Release OF node in pci_scan_device()'s error path (git-fixes). - PCI: endpoint: Fix missing destroy_workqueue() (git-fixes). - PCI: iproc: Fix return value of iproc_msi_irq_domain_alloc() (git-fixes). - PCI: thunder: Fix compile testing (git-fixes). - PM / devfreq: Use more accurate returned new_freq as resume_freq (git-fixes). - RDMA/addr: create addr_wq with WQ_MEM_RECLAIM flag (bsc#1183346). - RDMA/core: create ib_cm with WQ_MEM_RECLAIM flag (bsc#1183346). - RDMA/hns: Delete redundant abnormal interrupt status (git-fixes). - RDMA/hns: Delete redundant condition judgment related to eq (git-fixes). - RDMA/qedr: Fix error return code in qedr_iw_connect() (jsc#SLE-8215). - RDMA/srpt: Fix error return code in srpt_cm_req_recv() (git-fixes). - Revert 'arm64: vdso: Fix compilati
