(CVE-2022-41850)\n\nTamás Koczka discovered that the Bluetooth L2CAP implementation in the\nLinux kernel did not properly initialize memory in some situations. A\nphysically proximate attacker could possibly use this to expose sensitive\ninformation (kernel memory). (CVE-2022-42895)\n\nIt was discovered that the USB monitoring (usbmon) component in the Linux\nkernel did not properly set permissions on memory mapped in to user space\nprocesses. A local attacker could use this to cause a denial of service\n(system crash) or possibly execute arbitrary code. (CVE-2022-43750)\n\nIt was discovered that an integer overflow vulnerability existed in the\nBluetooth subsystem in the Linux kernel. A physically proximate attacker\ncould use this to cause a denial of service (system crash).\n(CVE-2022-45934)\n\nIt was discovered that the USB core subsystem in the Linux kernel did not\nproperly handle nested reset events. A local attacker with physical access\ncould plug in a specially crafted USB device to cause a denial of service\n(kernel deadlock). (CVE-2022-4662)\n\nArnaud Gatignol, Quentin Minster, Florent Saudel and Guillaume Teissier\ndiscovered that the KSMBD implementation in the Linux kernel did not\nproperly validate user-supplied data in some situations. An authenticated\nattacker could use this to cause a denial of service (system crash), expose\nsensitive information (kernel memory) or possibly execute arbitrary code.\n(CVE-2022-47940)\n\nIt was discovered that a race condition existed in the qdisc implementation\nin the Linux kernel, leading to a use-after-free vulnerability. A local\nattacker could use this to cause a denial of service (system crash) or\npossibly execute arbitrary code.
