Bug 219118

I'm not sure if this should be filed under Console/Framebuffers, Video(DRI - non Intel), or Video(Other).

I thought I'd created the bug in the correct location, https://gitlab.freedesktop.org/drm/amd/-/issues/3510 but no maintainer has commented or otherwise notably interacted with the report.  Initially I thought it was just an MPV bug since VLC didn't trigger the issue https://github.com/mpv-player/mpv/issues/14600 .

It looks like a developer's personal(?) drm-fixes-6.11 branch cherry picked the commit that appeared to fix the issue completely for my test cases: https://gitlab.freedesktop.org/agd5f/linux/-/commit/f3572db3c049b4d32bb5ba77ad5305616c44c7c1

However that isn't for the earlier 6.10.x series which also needs the fix, unless it's dead.

This appears to be a Swiss cheese sort of bug situation.  If software requests/provides contiguous buffers then the error results are more subtle, such as momentary video corruption if the kernel's access isn't out of bounds but rather rarely scrambled.  It's only when both the userspace and driver don't enforce contiguous buffer segments that out of bounds accesses result in a GPU reset and consequently terminated userspace.
