Description OSIDB Bzimport 2026-08-26 15:02:01 UTC 
In the Linux kernel, the following vulnerability has been resolved:

ASoC: tas2562: Validate values for volume writes

tas2562_volume_control_put() does not do any validation of the control
value written by userspace, it uses it to look up a value in a fixed
size array which can easily be overflowed and then writes whatever value
it gets back to the device.  Add validation that we are loading a value
we have in the array.
