AI-suggested
A patch is available and should be applied to affected linux-azure kernel versions. The vendor advisory confirms the issue is resolved in updated kernel releases. Users should update to the fixed versions to mitigate this vulnerability.
Description
A vulnerability in the Linux kernel's gpio mvebu driver was resolved. The issue involved improper freeing of generic chip data allocated by irq_alloc_domain_generic_chips(), which could lead to resource management errors. The fix explicitly calls irq_domain_remove_generic_chips() before irq_domain_remove() to ensure proper cleanup. This vulnerability affects specific linux-azure kernel versions and is rated as low severity.
