[PATCH] ASoC: es8316: fix register sync error in suspend/resume tests
by Pierre-Louis Bossart 22 Sep '22

22 Sep '22

The SOF CI tests report failures with the following error thrown kernel: es8316 i2c-ESSX8336:00: Unable to sync registers 0x0-0x1. -121 ES8336 only supports I2C read/write one byte a time, so we do need to set the .use_single_read and .use_single_write flags to avoid this sync issue.

KASAN: use-after-free Write in snd_rawmidi_receive
by Rondreis 22 Sep '22

22 Sep '22

Hello, When fuzzing the Linux kernel driver v5.18.0, the following crash was triggered. HEAD commit: 4b0986a3613c92f4ec1bdc7f60ec66fea135991f git tree: upstream kernel config: https://pastebin.com/raw/KecL2gaG console output: https://pastebin.com/raw/aJGZYGs4 Sorry for failing to extract the reproducer. But on other versions of Linux, I also triggered this crash. I would appreciate it if you have any idea how to solve this bug.

[PATCH] ASoC: SOF: ipc4-topology: Free the ida when IPC fails in sof_ipc4_widget_setup()
by Peter Ujfalusi 21 Sep '22

21 Sep '22

The allocated ida needs to be freed up if the IPC message fails since next time when we try again to set up the widget we are going to try to allocate another ID and given enough tries, we are going to run out of unique IDs.

possible deadlock in snd_rawmidi_free

Hello, When fuzzing the Linux kernel driver v6.0-rc4, the following crash was triggered. HEAD commit: 7e18e42e4b280c85b76967a9106a13ca61c16179 git tree: upstream kernel config: https://pastebin.com/raw/xtrgsXP3 console output: https://pastebin.com/raw/9tabWDtu Sorry for failing to extract the reproducer, and the crash occurred at the moment of disconnecting the midi device. On other versions of Linux, I also triggered this crash. I would appreciate it if you have any idea how to solve this bug.
