Vulnerability from fkie_nvd - Published: 2024-04-17 11:15 - Updated: 2026-08-04 11:17

Severity

7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
7.0 (High) - CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H

Summary

In the Linux kernel, the following vulnerability has been resolved: RDMA/srpt: Do not register event handler until srpt device is fully setup Upon rare occasions, KASAN reports a use-after-free Write in srpt_refresh_port(). This seems to be because an event handler is registered before the srpt device is fully setup and a race condition upon error may leave a partially setup event handler in place. Instead, only register the event handler after srpt device initialization is complete.

No remote packet processing is involved in reaching the vulnerable window.\nAC:L - The attacker controls both sides of the race: repeated `rdma link add`/`del` of soft-RoCE devices re-enters `srpt_add_one()` at will, while concurrent netdev link flaps generate `IB_EVENT_PORT_ACTIVE`/`IB_EVENT_PORT_ERR` inside the unprotected window, and keeping the netdev down makes `rdma_query_gid()` fail to force the `err_port` free path.\nPR:L - `nldev_newlink` is gated only by `netlink_capable(skb, CAP_NET_ADMIN)`, which resolves against the netns-owning user namespace, so an unprivileged user satisfies it via `unshare -Urn`; RDMA_NL_NLDEV is explicitly allowed in non-init net namespaces and `rxe_newlink()` adds no further restriction.\nUI:N - The attacker triggers device registration and the async IB events entirely from their own processes; no action by any other user or administrator is required.\nS:U - The corruption is confined to kernel slab memory within the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The use-after-free on the freed `srpt_device`/`srpt_port` allocation lets the attacker reclaim the slab object with a chosen structure, turning the stale `sport` reference into a means of reading and disclosing arbitrary kernel memory.\nI:H - `srpt_refresh_port()` writes into the freed object \u2014 `sm_lid`, `lid`, a 16-byte `gid`, and two `snprintf()`-formatted strings \u2014 giving a multi-byte write into attacker-sprayed heap memory that can corrupt adjacent kernel structures and be leveraged for control-flow hijacking.\nA:H - Both failure modes crash the kernel: `schedule_work()` on a zeroed `work_struct` makes the kworker call a NULL `work-\u003efunc`, and the use-after-free write reliably produces oopses/panics."

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
