A flaw was found in include/asm-generic/tlb.h in the Linux kernel due to a race condition (unmap_mapping_range versus munmap). This issue allows a device driver to free a page while it still has stale TLB entries.

Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
