AI-suggested
A code refactor has been applied to fix the out-of-bounds access issue. Users should update to fixed versions of the Linux kernel that include this patch. Since this is a kernel-level vulnerability, applying the official kernel updates from the vendor or distribution is the recommended remediation. Patch status is not explicitly confirmed in the provided data; users should consult their Linux distribution's security advisories for the official fix.
Description
A vulnerability in the Linux kernel's ASoC Intel AVS component involves out-of-bounds access due to improper indexing of the init_configs array. The issue arises when an ID equal to or larger than the number of init_configs is used, leading to potential memory access violations. The code has been refactored to fix this by changing how config entries are accessed, eliminating the unsafe indexing. This vulnerability has a medium severity rating with a CVSS score of 5.5 and impacts specific Linux kernel versions.
