Descriptions

An issue was discovered in wcd9335_codec_enable_dec in sound/soc/codecs/wcd9335.c in the Linux kernel through 5.1.5. It uses kstrndup instead of kmemdup_nul, which allows attackers to have an unspecified impact via unknown vectors. NOTE: The vendor disputes this issues as not being a vulnerability because switching to kmemdup_nul() would only fix a security issue if the source string wasn't NUL-terminated, which is not the case

** EN DISPUTA ** Se detecto un problema en la función wcd9335_codec_enable_dec en el archivo sound/soc/codecs/wcd9335.c en el kernel de Linux hasta la versión 5.1.5. Se usa kstrndup en lugar de kmemdup_nul, lo que permite a los atacantes tener un impacto no especificado a través de vectores desconocidos. NOTA: El proveedor niega que esto no sea una vulnerabilidad porque cambiar a kmemdup_nul() solo solucionaría un problema de seguridad si la cadena de origen no estaba NUL-terminated, lo cual no es el caso.
