{"id":"USN-5073-3","summary":"linux-raspi2 vulnerabilities","details":"Norbert Slusarek discovered that the CAN broadcast manger (bcm) protocol\nimplementation in the Linux kernel did not properly initialize memory in\nsome situations. A local attacker could use this to expose sensitive\ninformation (kernel memory). (CVE-2021-34693)\n\nMurray McAllister discovered that the joystick device interface in the\nLinux kernel did not properly validate data passed via an ioctl(). A local\nattacker could use this to cause a denial of service (system crash) or\npossibly execute arbitrary code on systems with a joystick device\nregistered. (CVE-2021-3612)\n\nIt was discovered that the Virtio console implementation in the Linux\nkernel did not properly validate input lengths in some situations. A local\nattacker could possibly use this to cause a denial of service (system\ncrash).
