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

The following security bugs were fixed :

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).

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-2019-3819: 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. (bnc#1123161).

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-2019-7221: Fixed a use-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-2019-7308: 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-2019-8912: 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-2019-8980: 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-2019-9213: expand_downwards in mm/mmap.c lacked 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-2019-2024: A use-after-free when disconnecting a source was fixed which could lead to crashes. bnc#1129179).

The update package also includes non-security fixes. See advisory for details.

In the Linux kernel 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 (UAF) in sockfs_setattr. A local attacker can use this flaw to escalate privileges and take control of the system.(CVE-2019-8912)

(CVE-2019-8912)

An update of the linux package has been released.

The version of Palo Alto Networks PAN-OS running on the remote host is 7.1.x prior to 7.1.24 or 8.0.x prior to 8.0.18 or 8.1.x prior to 8.1.9 or 9.0.x prior to 9.0.3. It is, therefore, affected by a vulnerability.

- A privilege escalation vulnerability exists in the Linux kernel's sockfs_setattr. An unauthenticated, local attacker   can exploit this to gain privileged access to the system.
