CVE-2025-40338
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.
Affected versions
Linux kernel versions
5.19
and later are affected. Fixed in
6.17.8,
6.18
and their respective stable series.
