CVE-2022-48889 Information

Description

In the Linux kernel the following vulnerability has been resolved:

ASoC: Intel: sof-nau8825: fix module alias overflow

The maximum name length for a platform_device_id entry is 20 characters including the trailing NUL byte. The sof_nau8825.c file exceeds that which causes an obscure error message:

sound/soc/intel/boards/snd-soc-sof_nau8825.mod.c:35:45: error: illegal character encoding in string literal [-Werror-Winvalid-source-encoding] MODULE_ALIAS(\platform:adl_max98373_nau8825<U+0018>); ^~~~ include/linux/module.h:168:49: note: expanded from macro ‘MODULE_ALIAS’ ^~~~~~ include/linux/module.h:165:56: note: expanded from macro ‘MODULE_INFO’ ^~~~ include/linux/moduleparam.h:26:47: note: expanded from macro ‘__MODULE_INFO’ = __MODULE_INFO_PREFIX __stringify(tag) =\ info

I could not figure out how to make the module handling robust enough to handle this better but as a quick fix using slightly shorter names that are still unique avoids the build issue.
