The vulnerability of the kvm_set_cpuid function in the include/linux/slab.h library of the KVM virtualization subsystem in the Linux operating system allows a hacker to induce a service failure.

The vulnerability of the kvmsetcpuid function in the include/linux/slab.h library of the KVM virtualization subsystem in the Linux kernel is related to improper release of the kvmcpuidentry2 array. Exploiting this vulnerability can allow an attacker to cause a system failure...

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 ...
