The sof_ipc3_rx_msg() checks for minimum size of a new rx message but it is missing the check for upper limit. Corrupted or compromised firmware might be able to take advantage of this to cause out of bounds reads outside of the message area.

Thanks!
[1/1] ASoC: SOF: ipc3: Check for upper size limit for the received message commit: 989a3e4479177d0f4afab8be1960731bc0ffbbd0
All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying to this mail.
Thanks, Mark
