About this tag
The rdma rxe tag covers discussions about the RDMA (Remote Direct Memory Access) rxe driver, a software implementation of RDMA over Ethernet. Content includes a security vulnerability fix for CVE-2025-40061, which addresses a race condition in the rxe driver's worker loop that could lead to a use-after-free error. The fix restores proper draining semantics after the driver's code was migrated from tasklets to workqueues. System operators using RDMA/rxe-enabled kernels are advised to apply stable kernel updates or distribution backports. The tag is relevant for Linux kernel developers, system administrators, and IT professionals managing RDMA deployments.
