Vulnerability from fkie_nvd - Published: 2026-01-25 15:15 - Updated: 2026-10-19 19:17

Severity

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

Summary

In the Linux kernel, the following vulnerability has been resolved: net: can: j1939: j1939_xtp_rx_rts_session_active(): deactivate session upon receiving the second rts Since j1939_session_deactivate_activate_next() in j1939_tp_rxtimer() is called only when the timer is enabled, we need to call j1939_session_deactivate_activate_next() if we cancelled the timer. Otherwise, refcount for j1939_session leaks, which will later appear as | unregister_netdevice: waiting for vcan0 to become free. Usage count = 2. problem.

No hard-to-win race or condition outside attacker influence is required.\nPR:N - Received CAN/J1939 frames enter the vulnerable receive path without authentication or credential checks. In the highest reasonable deployment, the attacker is an unauthenticated peer on the J1939/CAN network.\nUI:N - No victim interaction is required once the target is running the J1939 stack with a bound socket. The attacker only needs to transmit the crafted J1939 frames.\nS:U - The bug affects kernel CAN/J1939 session and netdevice lifetime management within the same kernel security authority. It does not cross a VM, sandbox, IOMMU, or other separate security boundary.\nC:N - The bug is a reference-count leak caused by failing to deactivate a receiver session after cancelling its timer. The investigation did not identify memory disclosure, arbitrary read, or use-after-free behavior.\nI:N - The leaked references pin session/private/netdevice objects but do not provide attacker-controlled data modification or a write primitive. There is no evidence of control-flow corruption or persistent data tampering.\nA:H - The leaked J1939 session/private references pin the CAN net_device and can make unregister_netdevice wait indefinitely with a nonzero usage count. This is a persistent denial of service against network device or namespace teardown and can be retriggered."

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.
