CVE-2024-46738 is a use-after-free vulnerability in the Linux kernel VMware VMCI subsystem. The resource-removal logic in vmci_resource_remove() identified entries using only the context and resource portions of a handle, without validating the resource type. Distinct resource types can therefore share the same context and resource values. Removing one such resource may remove a different table entry while the intended object is freed, leaving a dangling pointer in the VMCI resource table. Subsequent resource-table operations can dereference the freed object.
