kernel: KVM: x86: Fix shadow paging use-after-free due to unexpected role
A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM x86 shadow paging mechanism. This vulnerability occurs when a host page directory entry PDE mapping is changed from within the guest, leading to an unexpected role mismatch in shadow paging. This mismatch can cause a...
kernel: KVM: x86: Fix shadow paging use-after-free due to unexpected GFN
A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine x86 shadow paging mechanism. This use-after-free vulnerability arises from incorrect handling of Guest Frame Numbers GFNs when guest page tables are modified. A local attacker with control over a guest virtual machine could...
