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.

Executive Summary

This vulnerability in the Linux kernel's ASoC Intel avs component involves sharing the 'name' pointer directly between components. When components are torn down, this sharing can cause use-after-free errors because the same memory is accessed after it has been freed. The fix duplicates the 'name' to prevent this issue and updates the order of operations to ensure the component's name is properly set before initialization.

Impact Analysis

The vulnerability can lead to use-after-free errors in the Linux kernel, which may cause system instability, crashes, or potentially allow an attacker to execute arbitrary code or cause denial of service by exploiting the memory corruption.
