Affected Products:
                    SUSE Linux Enterprise Real Time Extension 12-SP4

   An update that solves 32 vulnerabilities and has 122 fixes
   is now available.


   The SUSE Linux Enterprise 12 SP4 RT kernel was updated to receive various
   security and bugfixes.

   The following security bugs were fixed:

   - 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-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
   - 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).
   - CVE-2020-10766: Fixed an issue which allowed an attacker with a local
     account to disable SSBD protection (bnc#1172781).
   - CVE-2020-10767: Fixed an issue where Indirect Branch Prediction Barrier
     was disabled in certain circumstances, leaving the system open to a
     spectre v2 style attack (bnc#1172782).

     if k_ascii is called several times in a row (bnc#1172775).
   - CVE-2020-0543: Fixed a side channel attack against special registers
     which could have resulted in leaking of read values to cores other than
     the one which called it. This attack is known as Special Register Buffer
     Data Sampling (SRBDS) or "CrossTalk" (bsc#1154824).

     calls leadingch could have led to a memory leak (bsc#1171219).

     trigger a sync of excessive duration via an XFS v5 image with crafted

     hold an incorrect lock during the ioctl operation and trigger a race
     condition (bsc#1171218).
