Maybe the misbehaving driver is writing past the end of its requested space though, inadvertently? (I don't know if this is always called a "heap overflow" or if that's just Clang AddressSanitizer.)

That resulted in a wide variety of different failures, from the kernel oopsing to various userspace components crashing. It would be very unusual to have unexpected DMA trigger such a specific failure.
