An issue was discovered in the Linux kernel before 5.7.3, related to
mm/gup.c and mm/huge_memory.c. The get_user_pages (aka gup) implementation,
when used for a copy-on-write page, does not properly consider the
semantics of read operations and therefore can grant unintended write
access, aka CID-17839856fd58.
