    "summary": "In the Linux kernel, the following vulnerability has been resolved: media: nxp: imx8-isi: Fix streaming cleanup on release The current implementation unconditionally calls mxc_isi_video_cleanup_streaming() in mxc_isi_video_release(). This can lead to situations where any release call (like from a simple \"v4l2-ctl -l\") may release a currently streaming queue when called on such a device. This is reproducible on an i.MX8MP board by streaming from an ISI capture device using gstreamer: gst-launch-1.0 -v v4l2src device=/dev/videoX ! \\ video/x-raw,format=GRAY8,width=1280,height=800,framerate=1/120 ! \\ fakesink While this stream is running, querying the caps of the same device provokes the error state: v4l2-ctl -l -d /dev/videoX This results in the following trace: [ 155.452152] ------------[ cut here ]------------ [ 155.452163] WARNING: CPU: 0 PID: 1708 at drivers/media/platform/nxp/imx8-isi/imx8-isi-pipe.c:713 mxc_isi_pipe_irq_handler+0x19c/0x1b0 [imx8_isi] [ 157.004248] Modules linked in: cfg80211 rpmsg_ctrl rpmsg_char rpmsg_tty virtio_rpmsg_bus rpmsg_ns rpmsg_core rfkill nft_ct nf_conntrack nf_defrag_ipv6 nf_defrag_ipv4 nf_tables mcp251x6 [ 157.053499] CPU: 0 UID: 0 PID: 1708 Comm: python3 Not tainted 6.15.4-00114-g1f61ca5cad76 #1 PREEMPT [ 157.064369] Hardware name: imx8mp_board_01 (DT) [ 157.068205] pstate: 400000c5 (nZcv daIF -PAN -UAO -TCO -DIT -SSBS BTYPE=--) [ 157.075169] pc : mxc_isi_pipe_irq_handler+0x19c/0x1b0 [imx8_isi] [ 157.081195] lr : mxc_isi_pipe_irq_handler+0x38",
