Descriptions
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.
Se detectó un problema en el kernel de Linux versiones anteriores a 5.7.3, relacionado con los archivos mm/gup.c y mm/huge_memory.c. La implementación de la función get_user_pages (también se conoce como gup), cuando se usa para una página copy-on-write, no considera apropiadamente la semántica de las operaciones de lectura y, por lo tanto, puede otorgar acceso de escritura involuntario, también se conoce como CID-17839856fd58
