This is related to a capability check for the wrong task (bsc#1128378).\n- CVE-2019-8912: af_alg_release() in crypto/af_alg.c neglected to set a NULL value for a certain structure member, which could have led to a use-after-free in sockfs_setattr (bsc#1126284).\n- CVE-2018-12232: In net/socket.c there was a race condition between fchownat and close in cases where they target the same socket file descriptor, related to the sock_close and sockfs_setattr functions. fchownat did not increment the file descriptor reference count, which allowed close to set the socket to NULL during fchownat's execution, leading to a NULL pointer dereference and system crash (bsc#1127757).\n- 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#1124734).\n- 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 (bsc#1124729).\n","affected":[{"package":{"name":"kernel-livepatch-SLE15_Update_0","ecosystem":"SUSE:Linux Enterprise Live Patching 15","purl":"pkg:rpm/suse/kernel-livepatch-SLE15_Update_0&distro=SUSE%20Linux%20Enterprise%20Live%20Patching%2015"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"9-25.2"}]}],"ecosystem_specific":{"binaries":[{"kernel-livepatch-4_12_14-23-default":"9-25.2"}]},"database_specific":{"source":"https://ftp.suse.com/pub/projects/security/osv/SUSE-SU-2019:0740-1.json"}},{"package":{"name":"kernel-livepatch-SLE15_Update_1","ecosystem":"SUSE:Linux Enterprise Live Patching 15","purl":"pkg:rpm/suse/kernel-livepatch-SLE15_Update_1&distro=SUSE%20Linux%20Enterprise%20Live%20Patching%2015"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8-2.1"}]}],"ecosystem_specific":{"binaries":[{"kernel-livepatch-4_12_14-25_3-default":"8-2.1"}]},"database_specific":{"source":"https://ftp.suse.com/pub/projects/security/osv/SUSE-SU-2019:0740-1.json"}},{"package":{"name":"kernel-livepatch-SLE15_Update_0","ecosystem":"SUSE:Linux Enterprise Live Patching 15","purl":"pkg:rpm/suse/kernel-livepatch-SLE15_Update_0&distro=SUSE%20Linux%20Enterprise%20Live%20Patching%2015"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"9-25.2"}]}],"ecosystem_specific":{"binaries":[{"kernel-livepatch-4_12_14-23-default":"9-25.2"}]},"database_specific":{"source":"https://ftp.suse.com/pub/projects/security/osv/SUSE-SU-2019:0740-1.json"}},{"package":{"name":"kernel-livepatch-SLE15_Update_1","ecosystem":"SUSE:Linux Enterprise Live Patching 15","purl":"pkg:rpm/suse/kernel-livepatch-SLE15_Update_1&distro=SUSE%20Linux%20Enterprise%20Live%20Patching%2015"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8-2.1"}]}],"ecosystem_specific":{"binaries":[{"kernel-livepatch-4_12_14-25_3-default":"8-2.1"}]},"database_specific":{"source":"https://ftp.suse.com/pub/projects/security/osv/SUSE-SU-2019:0740-1.json"}}],"references":[{"type":"ADVISORY","url":"https://www.suse.com/support/update/announcement/2019/suse-su-20190740-1/"},{"type":"REPORT","url":"https://bugzilla.suse.com/1124729"},{"type":"REPORT","url":"https://bugzilla.suse.com/1124734"},{"type":"REPORT","url":"https://bugzilla.suse.com/1126284"},{"type":"REPORT","url":"https://bugzilla.suse.com/1127757"},{"type":"REPORT","url":"https://bugzilla.suse.com/1128378"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2018-12232"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2019-6974"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2019-7221"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2019-8912"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2019-9213"}]}
