{"id":"USN-5416-1","summary":"linux-oem-5.14 vulnerabilities","details":"Qiuhao Li, Gaoning Pan and Yongkang Jia discovered that the KVM\nimplementation in the Linux kernel did not properly perform guest page\ntable updates in some situations. An attacker in a guest vm could possibly\nuse this to crash the host OS. (CVE-2022-1158)\n\nIt was discovered that the implementation of X.25 network protocols in the\nLinux kernel did not terminate link layer sessions properly. A local\nattacker could possibly use this to cause a denial of service (system\ncrash). (CVE-2022-1516)\n\nIt was discovered that the 8 Devices USB2CAN interface implementation in\nthe Linux kernel did not properly handle certain error conditions, leading\nto a double-free. A local attacker could possibly use this to cause a\ndenial of service (system crash). (CVE-2022-28388)\n\nIt was discovered that the Microchip CAN BUS Analyzer interface\nimplementation in the Linux kernel did not properly handle certain error\nconditions, leading to a double-free. A local attacker could possibly use\nthis to cause a denial of service (system crash). (CVE-2022-28389)\n\nIt was discovered that the EMS CAN/USB interface implementation in the\nLinux kernel contained a double-free vulnerability when handling certain\nerror conditions. A local attacker could use this to cause a denial of\nservice (memory exhaustion).
