CVE-2022-50224: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: KVM: x86/mmu: Treat NX as a valid SPTE bit for NPT Treat the NX bit as valid when using NPT, as KVM will set the NX bit when the NX huge page mitigation is enabled mindblowing and trigger the WARN that fires on reserved SPTE bits...

CVE-2021-47094

In the Linux kernel, the following vulnerability has been resolved: KVM: x86/mmu: Don't advance iterator after restart due to yielding After dropping mmulock in the TDP MMU, restart the iterator during tdpiternext and do not advance the iterator. Advancing the iterator results in skipping the...

kernel: Linux kernel KVM: Denial of Service via incorrect NX bit handling in NPT

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM component. When KVM uses Nested Page Tables NPT with NX huge page mitigation enabled, it incorrectly handles the No-Execute NX bit in Shadow Page Table Entries SPTE. This improper handling can be triggered by a local attacker...
