CVE-2024-42080

Summary

CVE-2024-42080 is a vulnerability affecting the Linux kernel. This issue involves the RDMA/restrack subsystem where a struct rdma_restrack_entry's kern_name was incorrectly set to KBUILD_MODNAME during ib_create_cq(). If the module exits without properly deleting this entry, it may result in an invalid address access during rdma_restrack_clean(), potentially causing instability or crashes. This code was initially intended to help locate forgotten PD releases but is now deemed unnecessary and should be removed.
