kernel: KVM: x86/mmu: Zap _all_ roots when unmapping gfn range in TDP MMU

In the Linux kernel, the following vulnerability has been resolved: KVM: x86/mmu: Zap all roots when unmapping gfn range in TDP MMU Zap both valid and invalid roots when zapping/unmapping a gfn range, as KVM must ensure it holds no references to the freed page after returning from the unmap...

xen-kernel -- use after free in FIFO event channel code

The Xen Project reports: When the EVTCHNOPinitcontrol operation is called with a bad guest frame number, it takes an error path which frees a control structure without also clearing the corresponding pointer. Certain subsequent operations EVTCHNOPexpandarray or another EVTCHNOPinitcontrol, upon...

xen-kernel -- x86 shadow pagetables: address width overflow

The Xen Project reports: In the x86 shadow pagetable code, the guest frame number of a superpage mapping is stored in a 32-bit field. If a shadowed guest can cause a superpage mapping of a guest-physical address at or above 2^44 to be shadowed, the top bits of the address will be lost, causing an...
