CVE-2025-40338 Details
Description
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.
A use-after-free vulnerability has been addressed in the Linux kernel's ASoC Intel AVS component. The issue arose from directly sharing the 'name' pointer between components, which could lead to use-after-free errors when tearing down components. The vulnerability affects the ASoC framework, specifically in how component names are handled. The problem has been resolved by duplicating the name to prevent such errors. Additionally, the order of operations has been updated, as the framework previously did not override component names set before initialization, allowing for potential inconsistencies.
Users can apply the latest patches available in the Linux kernel stable tree to address this vulnerability.
