The following security bugs were fixed:
CVE-2020-15780: A lockdown bypass for loading unsigned modules using
ACPI table injection was fixed. (bsc#1173573)
CVE-2020-15393: Fixed a memory leak in usbtest_disconnect (bnc#1173514).
CVE-2020-12771: An issue was discovered in btree_gc_coalesce in
drivers/md/bcache/btree.c has a deadlock if a coalescing operation fails
(bnc#1171732).
CVE-2020-12888: The VFIO PCI driver mishandled attempts to access
disabled memory space (bnc#1171868).
CVE-2020-10773: Fixed a memory leak on s390/s390x, in the
cmm_timeout_hander in file arch/s390/mm/cmm.c (bnc#1172999).
CVE-2020-14416: Fixed a race condition in tty->disc_data handling in the
slip and slcan line discipline could lead to a use-after-free. This
affects drivers/net/slip/slip.c and drivers/net/can/slcan.c
(bnc#1162002).
CVE-2020-0305: Fixed a possible use-after-free due to a race condition
incdev_get of char_dev.c. This could lead to local escalation of
privilege. User interaction is not needed for exploitation (bnc#1174462).
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. This flaw allowed a local
attacker with user privileges to cause a denial of service (bnc#1173265).
CVE-2020-10781: Fixed a denial of service issue in the ZRAM
implementation (bnc#1173074).
CVE-2019-20908: Fixed incorrect access permissions for the efivar_ssdt
ACPI variable, which could be used by attackers to bypass lockdown or
secure boot restrictions (bnc#1173567).
CVE-2019-16746: Fixed a buffer overflow in net/wireless/nl80211.c,
related to invalid length checks for variable elements in a beacon head
(bnc#1152107).
CVE-2020-10135: Legacy pairing and secure-connections pairing
authentication in Bluetooth 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-2020-14331: Fixed a buffer over write in vgacon_scrollback_update()
(bnc#1174205).
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).
