  "description": "The Linux Kernel, the operating system core itself.\r\n\r\n\r\n\r\nSecurity Fix(es):\r\n\r\nA use-after-free flaw was found in the Linux kernel?s SGI GRU driver in the way the first gru_file_unlocked_ioctl function is called by the user, where a fail pass occurs in the gru_check_chiplet_assignment function. This flaw allows a local user to crash or potentially escalate their privileges on the system.(CVE-2022-3424)\r\n\r\nA flaw incorrect access control in the Linux kernel USB core subsystem was found in the way user attaches usb device. A local user could use this flaw to crash the system.(CVE-2022-4662)\r\n\r\nAn issue was discovered in the Linux kernel 5.10.x before 5.10.155. A use-after-free in io_sqpoll_wait_sq in fs/io_uring.c allows an attacker to crash the kernel, resulting in denial of service. finish_wait can be skipped. An attack can occur in some situations by forking a process and then quickly terminating it. NOTE: later kernel versions, such as the 5.15 longterm series, substantially changed the implementation of io_sqpoll_wait_sq.(CVE-2022-47946)\n\nA flaw NULL Pointer Dereference in the Linux kernel NTFS3 driver function attr_punch_hole() was found. A local user could use this flaw to crash the system.(CVE-2022-4842)",
