Vulnerability from fkie_nvd - Published: 2026-09-16 11:16 - Updated: 2026-09-16 15:18

Severity

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

Summary

In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Initialize NVMe abort_work once at submission qla_nvme_fcp_abort() and qla_nvme_ls_abort() ran INIT_WORK() on priv->abort_work immediately before schedule_work(). INIT_WORK() reinitializes the work_struct, resetting its list head and clearing the pending bit. If an abort is issued more than once for the same command (for example, concurrent transport teardown and a timeout-driven abort), the second INIT_WORK() reinitializes a work item that is already queued, which can corrupt the workqueue list and lead to crashes or a looping worker. Initialize priv->abort_work once at command submission, next to the existing per-command spin_lock_init(&priv->cmd_lock), and leave only schedule_work() in the abort paths. schedule_work() already does nothing when the work item is still pending, so a repeated abort no longer disturbs an in-flight work item. The command is not returned to the transport until the final kref_put()/release callback runs after abort_work has completed, so the work item is idle before priv is reused and the single submission-time INIT_WORK() is safe.

A Fibre Channel peer (compromised NVMe-FC target or zoned SAN device) can stall commands to force timeouts and concurrently drop the link or send LOGO/RSCN so nvme_fc tears down, both of which call ls_abort/fcp_abort. FC is a non-IP fabric, so the vector is adjacent.\nAC:L - A malicious NVMe-FC target controls both sides of the documented race: delaying completions triggers timeout-driven abort while a concurrent link-down or logout triggers teardown abort. INIT_WORK() on still-queued abort_work is then attacker-influenceable under I/O load, so complexity is low.\nPR:N - The attacker is a Fibre Channel peer and needs no host credentials or capabilities. Fabric zoning/WWPN is a topology restriction captured by Adjacent, not an OS privilege, and NVMe in-band authentication is optional and off by default.\nUI:N - With ql2xnvmeenable defaulting to on, an established NVMe-FC association issues keepalives and I/O without user action. The target can stall those commands and flap the link without anyone mounting a volume or running a tool.\nS:U - Impact is kernel workqueue list corruption in the same host kernel that runs qla2xxx. That is ordinary kernel memory-corruption impact, not a VM escape, IOMMU bypass, or other crossed security authority.\nC:H - INIT_WORK() on a queued work_struct resets its list head without unlinking it, corrupting the workqueue and creating a use-after-free of work items. That UAF can be used to read kernel memory, so confidentiality is high.\nI:H - The same workqueue UAF can overwrite adjacent objects and hijack work-\u003efunc when the worker runs a freed item, yielding an arbitrary-write / control-flow primitive, so integrity is high.\nA:H - The corrupted workqueue can oops, panic, or run a looping worker, crashing or hanging the kernel, so availability is high."

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.
