  script_tag(name:"insight", value:"A vulnerability was found in compare_netdev_and_ip in drivers/infiniband/core/cma.c in RDMA in the Linux Kernel. The improper cleanup results in out-of-boundary read, where a local user can utilize this problem to crash the system or escalation of privilege.(CVE-2023-2176)

An issue was discovered in arch/x86/kvm/vmx/nested.c in the Linux kernel before 6.2.8. nVMX on x86_64 lacks consistency checks for CR0 and CR4.(CVE-2023-30456)

An out-of-bounds(OOB) memory access vulnerability was found in vmwgfx driver in drivers/gpu/vmxgfx/vmxgfx_kms.c in GPU component in the Linux kernel with device file '/dev/dri/renderD128 (or Dxxx)'. This flaw allows a local attacker with a user account on the system to gain privilege, causing a denial of service(DoS).(CVE-2022-36280)

A use-after-free flaw was found in vhost_net_set_backend in drivers/vhost/net.c in virtio network subcomponent in the Linux kernel due to a double fget. This flaw could allow a local attacker to crash the system, and could even lead to a kernel information leak problem.(CVE-2023-1838)

CVE-2023-0160 kernel: possibility of deadlock in libbpf function sock_hash_delete_elem.(CVE-2023-0160)

A flaw was found in KVM. When calling the KVM_GET_DEBUGREGS ioctl, on 32-bit systems, there might be some uninitialized portions of the kvm_debugregs structure that could be copied to userspace, causing an information leak.(CVE-2023-1513)

A flaw that boot CPU could be vulnerable for the speculative execution behavior kind of attacks in the Linux kernel X86 CPU Power management options functionality was found in the way user resuming CPU from suspend-to-RAM. A local user could use this flaw to potentially get unauthorized access to some memory of the CPU similar to the speculative execution behavior kind of attacks.(CVE-2023-1637)");
