kernel: memory leak in genl_register_family() in net/netlink/genetlink.c
An issue was discovered in the Linux kernel before 5.0.6. There is a memory leak issue when idr_alloc() fails in genl_register_family() in net/netlink/genetlink.c.
A flaw was found in the genl_register_family function in the Linux kernel. An attacker able to induce the error conditions could use this flaw to crash the system. The highest threat from this vulnerability is to system availability.
Statement: This issue is rated as having Low impact because of the preconditions needed to trigger the error/resource cleanup code path (system-wide out-of-memory condition, high privileges or physical access). The generic netlink is a way for kernel modues to easily communicate with userspace using netlink. genl_register_fa
