Vulnerability from github – Published: 2025-12-09 18:30 – Updated: 2025-12-09 18:30

Details

In the Linux kernel, the following vulnerability has been resolved:

ASoC: Intel: avs: Do not share the name pointer between components

By sharing 'name' directly, tearing down components may lead to use-after-free errors. Duplicate the name to avoid that.

At the same time, update the order of operations - since commit cee28113db17 ("ASoC: dmaengine_pcm: Allow passing component name via config") the framework does not override component->name if set before invoking the initializer.
