The SUSE Linux Enterprise 15 kernel was updated to receive various security and bugfixes. The following security bugs were fixed: - CVE-2019-2024: A use-after-free when disconnecting a source was fixed which could lead to crashes. bnc#1129179). - CVE-2019-9213: expand_downwards in mm/mmap.c lacks a check for the mmap minimum address, which made it easier for attackers to exploit kernel NULL pointer dereferences on non-SMAP platforms. This is related to a capability check for the wrong task (bnc#1128166). - CVE-2019-8980: A memory leak in the kernel_read_file function in fs/exec.c allowed attackers to cause a denial of service (memory consumption) by triggering vfs_read failures (bnc#1126209). - CVE-2019-3819: A flaw was found in the function hid_debug_events_read() in drivers/hid/hid-debug.c file which may enter an infinite loop with certain parameters passed from a userspace. A local privileged user ('root') can cause a system lock up and a denial of service. Versions from v4.18 and newer are vulnerable (bnc#1123161). - CVE-2019-8912: af_alg_release() in crypto/af_alg.c neglects to set a NULL value for a certain structure member, which leads to a use-after-free in sockfs_setattr (bnc#1125907). - CVE-2019-7308: kernel/bpf/verifier.c performed undesirable out-of-bounds speculation on pointer arithmetic in various cases, including cases of different branches with different state or limits to sanitize, leading to side-channel attacks (bnc#1124055). - CVE-2019-3459, CVE-2019-3460: The Bluetooth stack suffered from two remote information leak vulnerabilities in the code that handles incoming L2cap configuration packets (bsc#1120758). - CVE-2019-7221: Fixed a user-after-free vulnerability in the KVM hypervisor related to the emulation of a preemption timer, allowing an guest user/process to crash the host kernel. (bsc#1124732). - CVE-2019-7222: Fixed an information leakage in the KVM hypervisor related to handling page fault exceptions, which allowed a guest user/process to use this flaw to leak the host's stack memory contents to a guest (bsc#1124735). - CVE-2019-6974: kvm_ioctl_create_device in virt/kvm/kvm_main.c mishandled reference counting because of a race condition, leading to a use-after-free (bnc#1124728). - CVE-2018-20669: Missing access control checks in ioctl of gpu/drm/i915 driver were fixed which might have lead to information leaks. (bnc#1122971).
