CVE-2026-90196NVD
Vulnerability Summary
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.
