CVE-2026-90196
Published Sep 17, 2026
Description
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.

Frequently Asked Questions
What is CVE-2026-90196? +
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.
How do I check if I'm vulnerable to CVE-2026-90196? +
