CVE-2025-38022 is a use-after-free vulnerability in the Linux kernel RDMA/core subsystem. During concurrent device renaming and device registration, ib_device_rename() modifies the device name while holding a lock, but kobject_uevent() accesses that name without corresponding lock protection. This race can cause a slab-use-after-free read in ib_register_device(), detected by KASAN. The demonstrated call chain involves Soft-RoCE (RXE) device registration through RDMA netlink operations. The fix adds locking around device-name access during kobject event generation.

A slab use-after-free read in the Linux kernel RDMA/core ib_register_device path. Affected Rocky Linux 10.1 kernel packages have security updates under CIQ advisory crlsa-2026_1690.
A use-after-free vulnerability in the Linux kernel's RDMA/core subsystem caused by concurrent device renaming and unlocked access to the device name during uevent processing. The fix adds lock protection around that access. The advisory assigns a CVSS v3 base score of 7.8, with local access and low privileges required and potential high confidentiality, integrity, and availability impacts. The recommended remediation is to update the Echo linux package and related packages to version 6.1.162-1 or later.
A Linux kernel RDMA/core use-after-free vulnerability caused by insufficient locking around device-name access during device registration and uevent processing. It affects Google COS packages sys-kernel/csql-kernel-6_1 and sys-kernel/lakitu-kernel-6_1 before version 18244.521.74.
