CVE-2022-1975
There is a sleep-in-atomic bug in /net/nfc/netlink.c that allows an attacker to crash the Linux kernel by simulating a nfc device from user-space. CVE-2022-1974 A 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-2022-1012 A memory leak problem was found in the TCP source port generation algorithm in net/ipv4/tcp.c due to the small table perturb size. This flaw may allow an attacker to information leak and may cause a denial of service problem. CVE-2022-0494 A kernel information leak flaw was identified in the scsi_ioctl function in drivers/scsi/scsi_ioctl.c in the Linux kernel. This flaw allows a local attacker with a special user privilege (CAP_SYS_ADMIN or CAP_SYS_RAWIO) to create issues with confidentiality. CVE-2022-0854 A memory leak flaw was found in the Linux kernel���s DMA subsystem, in the way a user calls DMA_FROM_DEVICE. This flaw allows a local user to read random memory from the kernel space. CVE-2022-1789 With shadow paging enabled, the INVPCID instruction results in a call to kvm_mmu_invpcid_gva. If INVPCID is executed with CR0.PG=0, the invlpg callback is not set and the result is a NULL pointer dereference. CVE-2022-28893 The SUNRPC subsystem in the Linux kernel through 5.17.2 can call xs_xprt_free before ensuring that sockets are in the intended state.

CVE-2022-1786 A 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-2022-1852 A NULL pointer dereference flaw was found in the Linux kernel���s KVM module, which can lead to a denial of service in the x86_emulate_insn in arch/x86/kvm/emulate.c. This flaw occurs while executing an illegal instruction in guest in the Intel CPU. CVE-2022-1729 A race condition was found the Linux kernel in perf_event_open() which can be exploited by an unprivileged user to gain root privileges. The bug allows to build several exploit primitives such as kernel address information leak, arbitrary execution, etc. CVE-2022-21499 KGDB and KDB allow read and write access to kernel memory, and thus should be restricted during lockdown. An attacker with access to a serial port could trigger the debugger so it is important that the debugger respect the lockdown mode when/if it is triggered.
