CVE-2026-68231

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