Description of the patch:
The SUSE Linux Enterprise 15 SP1 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...
