kernel: KVM: NULL pointer dereference in kvm_dirty_ring_push in virt/kvm/dirty_ring.c

A NULL pointer dereference issue was found in KVM when releasing a vCPU with dirty ring support enabled. This flaw allows an unprivileged local attacker on the host to issue specific ioctl calls, causing a kernel oops condition that results in a denial of service...

kernel: KVM: NULL pointer dereference in kvm_irq_delivery_to_apic_fast()

A flaw was found in the Linux kernel’s KVM when attempting to set a SynIC IRQ. This issue makes it possible for a misbehaving VMM to write to SYNIC/STIMER MSRs, causing a NULL pointer dereference. This flaw allows an unprivileged local attacker on the host to issue specific ioctl calls, causing a...

kernel: kernel info leak issue in pfkey_register

A vulnerability was found in the pfkeyregister function in net/key/afkey.c in the Linux kernel. This flaw allows a local, unprivileged user to gain access to kernel memory, leading to a system crash or a leak of internal kernel information...

kernel: KVM: cmpxchg_gpte can write to pfns outside the userspace region

A flaw was found in KVM. When updating a guest's page table entry, vmpgoff was improperly used as the offset to get the page's pfn. As vaddr and vmpgoff are controllable by user-mode processes, this flaw allows unprivileged local users on the host to write outside the userspace region and...

hw: cpu: information disclosure via Intel Software Guard Extensions (SGX) Platform

A flaw was found in hw. Sensitive information accessible by physical probing of the JTAG interface for some IntelR Processors with SGX may allow an unprivileged user to disclose information via physical access...
