kernel: KVM: nVMX: missing consistency checks for CR0 and CR4

A flaw was found in the KVM's Intel nested virtualization feature nVMX. The effective values of the guest CR0 and CR4 registers could differ from those included in the VMCS12. In rare circumstances i.e., kvmintel module loaded with parameters nested=1 and ept=0 this could allow a malicious guest ...

kernel: iommu/vt-d: Clean up si_domain in the init_dmars() error path

A memory leak flaw was found in the Linux kernel's Intel VT-d IOMMU driver in the initialization error path. A local user can trigger this issue when the initdmars function fails during IOMMU setup, causing the sidomain memory to remain allocated without being freed. This results in a permanent...

kernel: wifi: iwlwifi: dvm: Fix memcpy: detected field-spanning write backtrace

A vulnerability was discovered in the Intel wireless iwlwifi driver in the Linux kernel that could lead to a buffer overflow in the Driver Virtualization Module key handling code.
