CVE-2025-38582:
Linux Kernel vulnerability analysis and mitigation
Overview
CVE-2025-38582 is a vulnerability discovered in the Linux kernel affecting the RDMA/hns component. The vulnerability was disclosed on August 19, 2025, and involves a double destruction issue of rsv_qp in the error flow handling (NVD, Debian Tracker).
Technical details
The vulnerability occurs when rsv_qp is double destroyed in the error flow, first in free_mr_init(), and then in hns_roce_exit(). This leads to a list_del corruption where ffff589732eb9b50->next contains LIST_POISON1 (dead000000000100). The issue manifests in the RDMA/hns driver component of the Linux kernel (NVD).
Impact
The vulnerability affects multiple versions of the Linux kernel, including bullseye, bookworm, trixie, and sid distributions. Some versions like bullseye 5.10.223-1 and 5.10.237-1 have been fixed, while others remain vulnerable (Debian Tracker).
Mitigation and workarounds
The issue has been resolved by moving the free_mr_init() call into hns_roce_v2_init(). Several Linux distributions have released patches to address this vulnerability. For example, bullseye has been fixed in versions 5.10.223-1 and 5.10.237-1 (Debian Tracker).
