Description
In the Linux kernel before 4.20.14, expand_downwards in mm/mmap.c lacks a check for the mmap minimum address, which makes it easier for attackers to exploit kernel NULL pointer dereferences on non-SMAP platforms. This is related to a capability check for the wrong task.
A flaw was found in mmap in the Linux kernel allowing the process to map a null page. This allows attackers to abuse this mechanism to turn null pointer dereferences into workable exploits.
