CVE-2019-9213 (GCVE-0-2019-9213)

Vulnerability from cvelistv5 – Published: 2019-03-05 22:00 – Updated: 2024-08-04 21:38
VLAI
Summary
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.
