In the Linux kernel, the following vulnerability has been resolved: ASoC: SOF: validate topology volume range before allocation SOF treats the topology mixer min and max values as non-negative indices into its volume table. It stores them in signed fields, allocates max + 1 entries through an int argument, and later indexes the table with the stored range. An inverted range is invalid, while a maximum at or above INT_MAX cannot be represented safely after the increment or in the signed fields. Validate the complete range before storing it or allocating the table.
