(CVE-2015-1420) A underflow error was discovered in the Linux kernel's Ozmo Devices USB over WiFi host controller driver. A remote attacker could exploit this flaw to cause a denial of service (system crash) or potentially execute arbitrary code via a specially crafted packet. (CVE-2015-4001) A bounds check error was discovered in the Linux kernel's Ozmo Devices USB over WiFi host controller driver. A remote attacker could exploit this flaw to cause a denial of service (system crash) or potentially execute arbitrary code via a specially crafted packet. (CVE-2015-4002) A division by zero error was discovered in the Linux kernel's Ozmo Devices USB over WiFi host controller driver. A remote attacker could exploit this flaw to cause a denial of service (system crash). (CVE-2015-4003) Carl H Lunde discovered missing consistency checks in the the Linux kernel's UDF file system (CONFIG_UDF_FS). A local attacker could exploit this flaw to cause a denial of service (system crash) by using a corrupted file system image. (CVE-2015-4167) Daniel Borkmann reported a kernel crash in the Linux kernel's BPF filter JIT optimization. A local attacker could exploit this flaw to cause a denial of service (system crash).
