  "description": "The Linux Kernel, the operating system core itself.\r\n\r\nSecurity Fix(es):\r\n\nAn out-of-bound write vulnerability was identified within the netfilter subsystem which can be exploited to achieve privilege escalation to root.(CVE-2022-1972)\n\r\nA use-after-free flaw was found in the Linux kernel's NFC core functionality due to a race condition between kobject creation and delete. This vulnerability allows a local attacker with CAP_NET_ADMIN privilege to leak kernel information.(CVE-2022-1974)\n\nA use-after-free flaw was found in the Linux kernel’s io_uring subsystem in the way a user sets up a ring with IORING_SETUP_IOPOLL with more than one task completing submissions on this ring. This flaw allows a local user to crash or escalate their privileges on the system.(CVE-2022-1786)",
