Description

The SUSE Linux Enterprise 12 SP2 LTSS 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 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-2018-14633: A security flaw was found in the chap_server_compute_md5() function in the ISCSI target code in the Linux kernel in a way an authentication request from an ISCSI initiator is processed. (bnc#1107829).

CVE-2019-7221: The KVM implementation in the Linux kernel had a Use-after-Free (bnc#1124732).

CVE-2019-7222: The KVM implementation in the Linux kernel had an Information Leak (bnc#1124735).

CVE-2019-6974: kvm_ioctl_create_device in virt/kvm/kvm_main.c mishandled reference counting because of a race condition, which led to a use-after-free (bnc#1124728).

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