Summary
CVE-2025-39714 affecting package kernel for versions less than 6.6.104.2-1
Details

In the Linux kernel, the following vulnerability has been resolved:

media: usbtv: Lock resolution while streaming

When an program is streaming (ffplay) and another program (qv4l2) changes the TV standard from NTSC to PAL, the kernel crashes due to trying to copy to unmapped memory.

Changing from NTSC to PAL increases the resolution in the usbtv struct, but the video plane buffer isn't adjusted, so it overflows.

[hverkuil: call vb2isbusy instead of vb2isstreaming]
