CVE-2022-50134:
Linux Kernel vulnerability analysis and mitigation
Overview
CVE-2022-50134 is a vulnerability discovered in the Linux kernel affecting the RDMA/hfi1 subsystem. The issue was published on June 18, 2025, and involves a potential memory leak in the setup_base_ctxt() function (NVD, Wiz).
Technical details
The vulnerability occurs when setup_base_ctxt() allocates memory for uctxt->groups using hfi1_alloc_ctxt_rcv_groups(). When init_user_ctxt() fails, the allocated memory for uctxt->groups is not properly released, resulting in a memory leak. The issue exists because the cleanup routine fails to call hfi1_free_ctxt_rcv_groups() when init_user_ctxt() fails (NVD).
Impact
The vulnerability leads to memory leaks in the Linux kernel's RDMA/hfi1 subsystem, which could potentially result in system resource exhaustion over time (Wiz).
Mitigation and workarounds
The vulnerability has been fixed by adding proper memory cleanup using hfi1_free_ctxt_rcv_groups() when init_user_ctxt() fails. Users should update their Linux kernel to a patched version (Wiz).
