CVE-2024-36953

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2024-36953
In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: vgic-v2: Check for non-NULL vCPU in vgic_v2_parse_attr() vgic_v2_parse_attr() is responsible for finding the vCPU that matches the user-provided CPUID, which (of course) may not be valid. If the ID is invalid, kvm_get_vcpu_by_id() returns NULL, which isn't handled gracefully. Similar to the GICv3 uaccess flow, check that kvm_get_vcpu_by_id() actually returns something and fail the ioctl if not.

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: KVM: arm64: vgic-v2: Verifique vCPU que no sea NULL en vgic_v2_parse_attr() vgic_v2_parse_attr() es responsable de encontrar la vCPU que coincida con el CPUID proporcionado por el usuario, que (de curso) puede no ser válido. Si el ID no es válido, kvm_get_vcpu_by_id() devuelve NULL, que no se maneja correctamente. De manera similar al flujo de uaccess de GICv3, verifique que kvm_get_vcpu_by_id() realmente devuelva algo y falle el ioctl si no.
