A local attacker could use this\nto cause a denial of service (system crash) or possibly execute arbitrary\ncode. (CVE-2023-32233)\n\nGwangun Jung discovered that the Quick Fair Queueing scheduler\nimplementation in the Linux kernel contained an out-of-bounds write\nvulnerability. A local attacker could use this to cause a denial of service\n(system crash) or possibly execute arbitrary code. (CVE-2023-31436)\n\nReima Ishii discovered that the nested KVM implementation for Intel x86\nprocessors in the Linux kernel did not properly validate control registers\nin certain situations. An attacker in a guest VM could use this to cause a\ndenial of service (guest crash). (CVE-2023-30456)\n\nIt was discovered that the Broadcom FullMAC USB WiFi driver in the Linux\nkernel did not properly perform data buffer size validation in some\nsituations. A physically proximate attacker could use this to craft a\nmalicious USB device that when inserted, could cause a denial of service\n(system crash) or possibly expose sensitive information. (CVE-2023-1380)\n\nIt was discovered that the Human Interface Device (HID) support driver in\nthe Linux kernel contained a type confusion vulnerability in some\nsituations. A local attacker could use this to cause a denial of service\n(system crash). (CVE-2023-1073)\n\nWei Chen discovered that the DVB USB AZ6027 driver in the Linux kernel\ncontained a null pointer dereference when handling certain messages from\nuser space. A local attacker could use this to cause a denial of service\n(system crash).
