Vulnerability from fkie_nvd - Published: 2026-08-10 13:20 - Updated: 2026-08-19 17:20
Severity
Summary
In the Linux kernel, the following vulnerability has been resolved:
media: airspy: Return queued buffers on start_streaming() failure
The vb2 framework hands buffers to the driver via buf_queue() before
calling start_streaming(). If start_streaming() returns an error
without first returning those buffers via vb2_buffer_done(),
vb2_start_streaming() fires WARN_ON(owned_by_drv_count) and the queued
buffers leak.
airspy_start_streaming() returned -ENODEV early when the USB device had
been disconnected (s->udev == NULL) without returning any buffers that
buf_queue() had already accepted. Take v4l2_lock first and jump to the
existing err_clear_bit label, which already drains s->queued_bufs via
vb2_buffer_done(..., VB2_BUF_STATE_QUEUED) before unlocking.
This mirrors the uvcvideo fix in commit 4cf3b6fd54eb ("media: uvcvideo:
Return queued buffers on start_streaming() failure").

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.
