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.
