A\nlocal attacker could use this to expose sensitive information.\n(CVE-2019-14615)\n\nIt was discovered that a race condition existed in the Virtual Video Test\nDriver in the Linux kernel. An attacker with write access to /dev/video0 on\na system with the vivid module loaded could possibly use this to gain\nadministrative privileges. (CVE-2019-18683)\n\nIt was discovered that the btrfs file system in the Linux kernel did not\nproperly validate metadata, leading to a NULL pointer dereference. An\nattacker could use this to specially craft a file system image that, when\nmounted, could cause a denial of service (system crash). (CVE-2019-18885)\n\nIt was discovered that multiple memory leaks existed in the Marvell WiFi-Ex\nDriver for the Linux kernel. A local attacker could possibly use this to\ncause a denial of service (kernel memory exhaustion). (CVE-2019-19057)\n\nIt was discovered that the crypto subsystem in the Linux kernel did not\nproperly deallocate memory in certain error conditions. A local attacker\ncould use this to cause a denial of service (kernel memory exhaustion).\n(CVE-2019-19062)\n\nIt was discovered that the Realtek rtlwifi USB device driver in the Linux\nkernel did not properly deallocate memory in certain error conditions. A\nlocal attacker could possibly use this to cause a denial of service (kernel\nmemory exhaustion). (CVE-2019-19063)\n\nDan Carpenter discovered that the AppleTalk networking subsystem of the\nLinux kernel did not properly handle certain error conditions, leading to a\nNULL pointer dereference. A local attacker could use this to cause a denial\nof service (system crash). (CVE-2019-19227)\n\nIt was discovered that the KVM hypervisor implementation in the Linux\nkernel did not properly handle ioctl requests to get emulated CPUID\nfeatures. An attacker with access to /dev/kvm could use this to cause a\ndenial of service (system crash). (CVE-2019-19332)\n\nIt was discovered that the B2C2 FlexCop USB device driver in the Linux\nkernel did not properly validate device metadata.
