The SUSE Linux Enterprise 12 SP5 kernel was updated to receive various security and bugfixes. The following security bugs were fixed: - CVE-2020-14331: A buffer over write in vgacon_scroll was fixed (bnc#1174205). - CVE-2020-10135: Legacy pairing and secure-connections pairing authentication in Bluetooth BR/EDR Core Specification v5.2 and earlier may have allowed an unauthenticated user to complete authentication without pairing credentials via adjacent access. An unauthenticated, adjacent attacker could impersonate a Bluetooth BR/EDR master or slave to pair with a previously paired remote device to successfully complete the authentication procedure without knowing the link key (bnc#1171988). - CVE-2020-0305: In cdev_get of char_dev.c, there is a possible use-after-free due to a race condition. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation (bnc#1174462). - CVE-2019-20908: An issue was discovered in drivers/firmware/efi/efi.c where incorrect access permissions for the efivar_ssdt ACPI variable could be used by attackers to bypass lockdown or secure boot restrictions, aka CID-1957a85b0032 (bnc#1173567). - CVE-2020-10781: zram sysfs resource consumption was fixed (bnc#1173074). - CVE-2020-15780: An issue was discovered in drivers/acpi/acpi_configfs.c where injection of malicious ACPI tables via configfs could be used by attackers to bypass lockdown and secure boot restrictions, aka CID-75b0cea7bf30 (bnc#1173573). - CVE-2020-15393: usbtest_disconnect in drivers/usb/misc/usbtest.c had a memory leak, aka CID-28ebeb8db770 (bnc#1173514). - CVE-2020-12771: btree_gc_coalesce in drivers/md/bcache/btree.c had a deadlock if a coalescing operation fails (bnc#1171732). - CVE-2019-16746: net/wireless/nl80211.c did not check the length of variable elements in a beacon head, leading to a buffer overflow (bnc#1152107). - CVE-2020-12888: The VFIO PCI driver mishandled attempts to access disabled memory space (bnc#1171868). - CVE-2020-10769: A buffer over-read flaw was found in crypto_authenc_extractkeys in crypto/authenc.c in the IPsec Cryptographic algorithm's module, authenc. When a payload longer than 4 bytes, and is not following 4-byte alignment boundary guidelines, it causes a buffer over-read threat, leading to a system crash. This flaw allowed a local attacker with user privileges to cause a denial of service (bnc#1173265). - CVE-2020-10773: A kernel stack information leak on s390/s390x was fixed (bnc#1172999). - CVE-2020-14416: A race condition in tty->disc_data handling in the slip and slcan line discipline could lead to a use-after-free, aka CID-0ace17d56824. This affects drivers/net/slip/slip.c and drivers/net/can/slcan.c (bnc#1162002). The following non-security bugs were fixed: - ACPI: GED: add support for _Exx / _Lxx handler methods (bsc#1111666). - ACPI: GED: use correct trigger type field in _Exx / _Lxx handling (bsc#1111666). - ACPI: NFIT: Fix unlock on error in scrub_show() (bsc#1171753). - ACPI: sysfs: Fix pm_profile_attr type (bsc#1111666). - ACPI: video: Use native backlight on Acer Aspire 5783z (bsc#1111666). - ACPI: video: Use native backlight on Acer TravelMate 5735Z (bsc#1111666). - ALSA: hda - let hs_mic be picked ahead of hp_mic (bsc#1111666). - ALSA: hda/realtek - Enable Speaker for ASUS UX533 and UX534 (bsc#1111666). - ALSA: lx6464es - add support for LX6464ESe pci express variant (bsc#1111666). - ALSA: opl3: fix infoleak in opl3 (bsc#1111666). - ALSA: usb-audio: add quirk for MacroSilicon MS2109 (bsc#1111666). - ALSA: usb-audio: Fix packet size calculation (bsc#1111666). - ALSA: usb-audio: Improve frames size computation (bsc#1111666). - amdgpu: a NULL ->mm does not mean a thread is a kthread (git-fixes). - ath9k: Fix general protection fault in ath9k_hif_usb_rx_cb (bsc#1111666). - ath9k: Fix use-after-free Read in ath9k_wmi_ctrl_rx (bsc#1111666). - ath9k: Fix use-after-free Write in ath9k_htc_rx_msg (bsc#1111666). - ath9x: Fix stack-out-of-bounds Write in ath9k_hif_usb_rx_cb (bsc#1111666). - ax25: fix setsockopt(SO_BINDTODEVICE) (networking-stable-20_05_27). - b43: Fix connection problem with WPA3 (bsc#1111666). - b43_legacy: Fix connection problem with WPA3 (bsc#1111666). - be2net: fix link failure after ethtool offline test (git-fixes). - block, bfq: add requeue-request hook (bsc#1104967 bsc#1171673). - block, bfq: postpone rq preparation to insert or merge (bsc#1104967 bsc#1171673).
