In the Linux kernel, the following vulnerability has been resolved:
ASoC: Intel: sof-nau8825: fix module alias overflow
The maximum name length for a platformdeviceid 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-sofnau8825.mod.c:35:45: error: illegal character encoding in string literal [-Werror,-Winvalid-source-encoding] MODULEALIAS("platform:adlmax98373nau8825<U+0018><AA>"); ^~~~ include/linux/module.h:168:49: note: expanded from macro 'MODULEALIAS' ^~~~~~ include/linux/module.h:165:56: note: expanded from macro 'MODULEINFO' ^~~~ include/linux/moduleparam.h:26:47: note: expanded from macro '_MODULEINFO' = _MODULEINFOPREFIX _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.
