Description OSIDB Bzimport 2026-09-17 18:08:15 UTC
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.
