Summary
CVE-2021-46970: A vulnerability in the Linux kernel's MHI driver has been addressed. The issue arose from the addition of WQ_HIGHPRI and WQ_MEM_RECLAIM flags to a dedicated workqueue for state-change work. However, this work does not guarantee progress under memory pressure and even waits on memory allocations. The presence of WQ_MEM_RECLAIM caused a warning in check_flush_dependency() since it flushed non-reclaim workqueue events. This vulnerability could lead to unnecessary warnings and potential performance issues.
