failure to limit DMA buffer size (bsc#1004706).\n- CVE-2016-8910: The rtl8139_cplus_transmit function in hw/net/rtl8139.c allowed local guest OS administrators to cause a denial of service (infinite loop and CPU consumption) by leveraging failure to limit the ring descriptor count (bsc#1006538).\n- CVE-2016-8909: The intel_hda_xfer function in hw/audio/intel-hda.c allowed local guest OS administrators to cause a denial of service (infinite loop and CPU consumption) via an entry with the same value for buffer length and pointer position (bsc#1006536).\n- CVE-2016-7994: Memory leak in virtio_gpu_resource_create_2d (bsc#1003613).\n- CVE-2016-9104: Integer overflow leading to OOB access in 9pfs (bsc#1007493).\n- CVE-2016-8667: The rc4030_write function in hw/dma/rc4030.c allowed local guest OS administrators to cause a denial of service (divide-by-zero error and QEMU process crash) via a large interval timer reload value (bsc#1004702).\n- CVE-2016-7907: The pcnet_rdra_addr function in hw/net/pcnet.c allowed local guest OS administrators to cause a denial of service (infinite loop and QEMU process crash) by setting the (1) receive or (2) transmit descriptor ring length to 0 (bsc#1002549).\n\nThese non-security issues were fixed:\n- Change kvm-supported.txt to be per-architecture documentation, stored in the\n  package documentation directory of each per-arch package (bsc#1005353).\n- Update support doc to include current ARM64 (AArch64) support stance (bsc#1005374).\n- Fix migration failure when snapshot also has been done (bsc#1008148).\n- Change package post script udevadm trigger calls to be device specific (bsc#1002116).\n- Add qmp-commands.txt documentation file back in. It was inadvertently dropped.\n- Add an x86 cpu option (l3-cache) to specify that an L3 cache is present and\n  another option (cpuid-0xb) to enable the cpuid 0xb leaf (bsc#1007769).\n\nFor Leap 42.2 this update also enabled the smartcard support (bsc#1007263).\n","status":"published","published":"2016-11-22T14:26:40Z","modified":"2026-02-04T04:14:51.939445Z","updated_at":"2026-11-02T15:53:43.438985Z"},{"id":"USN-3261-1","title":"qemu vulnerabilities","description":"Zhenhao Hong discovered that QEMU incorrectly handled the Virtio GPU\ndevice.
