Detailsinfo

A vulnerability classified as problematic was found in Linux Kernel up to 6.6.147/6.12.100/6.18.41/7.1.5. Affected by this vulnerability is the function airspy_start_streaming of the component airspy. The manipulation with an unknown input leads to a denial of service vulnerability. The CWE definition for the vulnerability is CWE-404. The product does not release or incorrectly releases a resource before it is made available for re-use. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

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 advisory is shared at git.kernel.org. This vulnerability is known as CVE-2026-68231 since 07/30/2026. The exploitation appears to be easy. An attack has to be approached locally. It demands that the victim is doing some kind of user interaction. Technical details are known, but no exploit is available.

Upgrading to version 6.6.148, 6.12.101, 6.18.42, 7.1.6 or 7.2-rc1 eliminates this vulnerability. Applying the patch 877686a74ecdc93dcaee09dbac566e819059c9e7/cd42623d698b59f1fe5768f78a4101c28d5feb2e/73bd2779865372b1017d4f555b45270aa2d0d710/170fcc945bc094b1c956bf555c070692826a3eff/04344d0b4929caa94c0df72f767752aa0935ef5d is able to eliminate this problem.
