NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-9576 (bsc#1019079).\n- CVE-2016-9794: Race condition in the snd_pcm_period_elapsed function in sound/core/pcm_lib.c in the ALSA subsystem in the Linux kernel allowed local users to cause a denial of service (use-after-free) or possibly have unspecified other impact via a crafted SNDRV_PCM_TRIGGER_START command (bsc#1013543).\n- CVE-2016-8632: The tipc_msg_build function in net/tipc/msg.c in the Linux kernel did not validate the relationship between the minimum fragment length and the maximum packet size, which allowed local users to gain privileges or cause a denial of service (heap-based buffer overflow) by leveraging the CAP_NET_ADMIN capability (bsc#1012852).\n- CVE-2016-9576: The blk_rq_map_user_iov function in block/blk-map.c in the Linux kernel did not properly restrict the type of iterator, which allowed local users to read or write to arbitrary kernel memory locations or cause a denial of service (use-after-free) by leveraging access to a /dev/sg device (bsc#1014271).\nbefore 4.8.14\n","id":"SUSE-SU-2017:0228-1","modified":"2017-01-20T12:30:45Z","published":"2017-01-20T12:30:45Z","references":[{"type":"ADVISORY","url":"https://www.suse.com/support/update/announcement/2017/suse-su-20170228-1/"},{"type":"REPORT","url":"https://bugzilla.suse.com/1012852"},{"type":"REPORT","url":"https://bugzilla.suse.com/1013543"},{"type":"REPORT","url":"https://bugzilla.suse.com/1014271"},{"type":"REPORT","url":"https://bugzilla.suse.com/1019079"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2016-10088"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2016-8632"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2016-9576"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2016-9794"}],"related":["CVE-2016-10088","CVE-2016-8632","CVE-2016-9576","CVE-2016-9794"],"summary":"Security update for Linux Kernel Live Patch 1 for SLE 12 SP2"}
