CVE-2024-36953

CVE-2024-36953 affects the Linux kernel KVM for arm64 with vgic-v2. The issue: vgic_v2_parse_attr() searches for a vCPU matching the CPUID and may receive a NULL from kvm_get_vcpu_by_id() if the ID is invalid. Unlike the safe GICv3 flow, the code did not verify the returned vCPU object. Affected ...

kernel: Linux kernel KVM: Denial of Service in nested SVM due to TSC multiplier manipulation

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM nested SVM nSVM module. A local attacker with low privileges in a nested virtual machine can manipulate the Timestamp Counter TSC multiplier and CPUID features. This manipulation can trigger a kernel warning, leading to a...
