CVE-2019-9213 (retired)

Priority
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.
Ubuntu-Description
Jann Horn discovered that the mmap implementation in the Linux kernel did
not properly check for the mmap minimum address in some situations. A local
attacker could use this to assist exploiting a kernel NULL pointer
dereference vulnerability.
