Linux Kernel RDMA/rxe Slab-Use-After-Free Vulnerability

Vulnerability

A slab-use-after-free vulnerability has been identified in the Linux kernel's RDMA/rxe component. This issue arises in the 'rxe_create_cq' function, where resource cleanup is improperly managed, leading to a use-after-free condition. The vulnerability occurs because some memory resources are freed prematurely, creating the potential for a slab-based memory corruption exploit.
