The SUSE Linux Enterprise 12 SP5 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) The following non-security bugs were fixed: - ACPI / hotplug / PCI: Fix reference count leak in enable_slot() (git-fixes). - ACPI: CPPC: Replace cppc_attr with kobj_attribute (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). - ACPICA: Enable sleep button on ACPI legacy wake (bsc#1181383). - ALSA: aloop: Fix initialization of controls (git-fixes). - ALSA: bebob/oxfw: fix Kconfig entry for Mackie d.2 Pro (git-fixes). - ALSA: core: remove redundant spin_lock pair in snd_card_disconnect (git-fixes). - ALSA: emu8000: Fix a use after free in snd_emu8000_create_mixer (git-fixes). - ALSA: hda/conexant: Re-order CX5066 quirk table entries (git-fixes). - ALSA: hda/realtek: Re-order ALC269 Lenovo quirk table entries (git-fixes). - ALSA: hda/realtek: Re-order ALC269 Sony quirk table entries (git-fixes). - ALSA: hda/realtek: Re-order ALC882 Acer quirk table entries (git-fixes). - ALSA: hda/realtek: Re-order ALC882 Sony quirk table entries (git-fixes). - ALSA: hda/realtek: Remove redundant entry for ALC861 Haier/Uniwill devices (git-fixes). - ALSA: hda/realtek: reset eapd coeff to default value for alc287 (git-fixes). - ALSA: hdsp: do not disable if not enabled (git-fixes). - ALSA: hdspm: do not disable if not enabled (git-fixes). - ALSA: line6: Fix racy initialization of LINE6 MIDI (git-fixes). - ALSA: rme9652: do not disable if not enabled (git-fixes). - ALSA: sb: Fix two use after free in snd_sb_qsound_build (git-fixes). - ALSA: usb-audio: Add MIDI quirk for Vox ToneLab EX (git-fixes). - ALSA: usb-audio: Add error checks for usb_driver_claim_interface() calls (git-fixes). - ALSA: usb: midi: do not return -ENOMEM when usb_urb_ep_type_check fails (git-fixes). - ARM: footbridge: fix PCI interrupt mapping (git-fixes). - ASoC: cs35l33: fix an error code in probe() (git-fixes). - ASoC: cs42l42: Regmap must use_single_read/write (git-fixes). - ASoC: fsl_esai: Fix TDM slot setup for I2S mode (git-fixes). - ASoC: intel: atom: Stop advertising non working S24LE support (git-fixes). - ASoC: rt286: Generalize support for ALC3263 codec (git-fixes). - ASoC: rt286: Make RT286_SET_GPIO_* readable and writable (git-fixes). - ASoC: wm8960: Fix wrong bclk and lrclk with pll enabled for some chips (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: initialize skb_queue_head at l2cap_chan_create() (git-fixes). - Drivers: hv: vmbus: Increase wait time for VMbus unload (bsc#1185724). - Drivers: hv: vmbus: Initialize unload_event statically (bsc#1185724). - Drivers: hv: vmbus: Use after free in __vmbus_open() (git-fixes). - EDAC/amd64: Gather hardware information early (bsc#1180552). - EDAC/amd64: Make struct amd64_family_type global (bsc#1180552). - EDAC/amd64: Save max number of controllers to family type (bsc#1180552). - HID: alps: fix error return code in alps_input_configured() (git-fixes). - HID: plantronics: Workaround for double volume key presses (git-fixes). - HID: wacom: Assign boolean values to a bool variable (git-fixes). - HID: wacom: set EV_KEY and EV_ABS only for non-HID_GENERIC type of devices (git-fixes). - Input: elants_i2c - do not bind to i2c-hid compatible ACPI instantiated devices (git-fixes). - Input: i8042 - fix Pegatron C15B ID entry (git-fixes). - Input: nspire-keypad - enable interrupts only when opened (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). - NFC: fix possible resource leak (git-fixes). - NFC: fix resource leak when target index is invalid (git-fixes). - NFC: nci: fix memory leak in nci_allocate_device (git-fixes). - NFSv4: Replace closed stateids with the 'invalid special stateid' (bsc#1185481). - 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). - RDMA/hns: Delete redundant condition judgment related to eq (bsc#1104427). - RDMA/srpt: Fix error return code in srpt_cm_req_recv() (bsc#1103992). - SUNRPC in case of backlog, hand free slots directly to waiting task (bsc#1185428). - SUNRPC: More fixes for backlog congestion (bsc#1185428). - USB: Add LPM quirk for Lenovo ThinkPad USB-C Dock Gen2 Ethernet (git-fixes). - USB: Add reset-resume quirk for WD19's Realtek Hub (git-fixes). - USB: serial: fix return value for unsupported ioctls (git-fixes). - USB: serial: usb_wwan: fix unprivileged TIOCCSERIAL (git-fixes). - USB: trancevibrator: fix control-request direction (git-fixes). - af_packet: fix the tx skb protocol in raw sockets with ETH_P_ALL (bsc#1176081). - ata: libahci_platform: fix IRQ check (git-fixes). -
