Уязвимость компонента mm/gup.c операционной системы Linux, позволяющая нарушителю повысить свои привилегии

Уязвимость функции aio_mount в fs/aio.c ядра операционной системы Android, позволяющая нарушителю обойти политику ограничений и повысить свои привилегии

The aio_mount function in fs/aio.c in the Linux kernel before 4.7.7 does not properly restrict execute access, which makes it easier for local users to bypass intended SELinux W^X policy restrictions, and consequently gain privileges, via an io_setup system call.

Race condition in mm/gup.c in the Linux kernel 2.x through 4.x before 4.8.3 allows local users to gain privileges by leveraging incorrect handling of a copy-on-write (COW) feature to write to a read-only memory mapping, as exploited in the wild in October 2016, aka "Dirty COW."
