[1/4] firmware: cs_dsp: Fix overflow checking of wmfw header commit: 3019b86bce16fbb5bc1964f3544d0ce7d0137278 [2/4] firmware: cs_dsp: Return error if block header overflows file commit: 959fe01e85b7241e3ec305d657febbe82da16a02 [3/4] firmware: cs_dsp: Validate payload length before processing block commit: 6598afa9320b6ab13041616950ca5f8f938c0cf1 [4/4] firmware: cs_dsp: Prevent buffer overrun when processing V2 alg headers commit: 2163aff6bebbb752edf73f79700f5e2095f3559e 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
This series fixes various missing length checks when processing variable-length data from the firmware file. These could have caused overrunning the end of firmware file buffer, or wild pointer accesses.
