jira VULN-70503 cve CVE-2022-50050 commit-author Takashi Iwai <tiwai@suse.de> commit 94c1ceb upstream-diff | Adjusted context due to missing commit 71778f7("ASoC: SOF: Intel: hda: Define rom_status_reg in sof_intel_dsp_desc") snprintf() returns the would-be-filled size when the string overflows the given buffer size, hence using this value may result in the buffer overflow (although it's unrealistic). This patch replaces with a safer version, scnprintf() for papering over such a potential issue. Fixes: 29c8e43 ("ASoC: SOF: Intel: hda: add extended rom status dump to error log") Signed-off-by: Takashi Iwai <tiwai@suse.de> Link: https://lore.kernel.org/r/20220801165420.25978-4-tiwai@suse.de Signed-off-by: Mark Brown <broonie@kernel.org> (cherry picked from commit 94c1ceb) Signed-off-by: Roxana Nicolescu <rnicolescu@ciq.com>

DESCRIPTION
Not a clean cherry pick due to missing
71778f7("ASoC: SOF: Intel: hda: Define rom_status_reg in sof_intel_dsp_desc").
Not added as a pre-req because it is part of a bigger patchset upstream.
https://lore.kernel.org/all/20220414184817.362215-14-pierre-louis.bossart@linux.intel.com/
Otherwise, the change is straightfoward.

That's due tot missing commit
71778f7("ASoC: SOF: Intel: hda: Define rom_status_reg in sof_intel_dsp_desc").
Not added because it was part of a bigger patchset
https://lore.kernel.org/all/20220414184817.362215-14-pierre-louis.bossart@linux.intel.com/
And the last one is due to missing commit
34bfba9 ("ASoC: SOF: Intel: hda: Use DEBUG log level for optional prints").
