CVE-2024-57935: RDMA/hns: Fix accessing invalid dip_ctx during destroying QP

In the Linux kernel, the following vulnerability has been resolved: RDMA/hns: Fix accessing invalid dip_ctx during destroying QP If it fails to modify QP to RTR, dip_ctx will not be attached. And during detroying QP, the invalid dip_ctx pointer will be accessed.

Security readout for executives and security teams

Plain-English summary

This Linux kernel issue can make the RDMA/hns driver access an invalid internal pointer while cleaning up a Queue Pair after a failed state change. The business risk is currently unclear because no CVSS score, CWE, exploit report, or impact statement is provided in the source bundle.

Executive priority

Treat as targeted infrastructure hygiene unless RDMA/hns is used in production. For RDMA-enabled Linux fleets, prioritize patch validation because kernel driver pointer faults can affect host reliability even when exploitation evidence is absent.

Technical view

The flaw is in RDMA/hns Queue Pair teardown. If modifying a QP to RTR fails, dip_ctx is not attached, but the destroy path still accesses the invalid dip_ctx pointer. The referenced Linux stable commits resolve that invalid access condition.

Likely exposure

Exposure appears limited to Linux systems using the RDMA/hns kernel driver and affected kernel builds. Systems without this driver loaded or relevant RDMA hardware paths are less likely to be exposed. The source bundle does not clearly define affected version ranges.

Exploitation context

The source bundle does not report active exploitation, and KEV status is false. It describes a kernel driver cleanup bug, not a public exploit path. Any exploitability beyond local or driver-reachable fault conditions is not established by the cited sources.

Researcher notes

The key condition is QP modify-to-RTR failure followed by destroy. The incomplete public metadata leaves impact, affected ranges, and triggerability uncertain. Focus analysis on patched RDMA/hns teardown logic and downstream vendor backports.

Mitigation direction

  • Apply Linux vendor kernel updates that include the referenced stable fixes.
  • Check distribution advisories for exact affected and fixed kernel packages.
  • Prioritize systems using RDMA/hns or relevant RDMA hardware.
  • If RDMA/hns is unnecessary, review vendor-supported hardening or disablement options.

Validation and detection

  • Inventory Linux hosts for kernel versions and loaded RDMA/hns driver usage.
  • Map installed kernels against distribution advisories for CVE-2024-57935.
  • Confirm fixed commits or downstream backports are present.
  • Review kernel logs for RDMA/hns QP failure or teardown errors.
