What is CVE-2019-16230?
CVE-2019-16230 is a medium-severity vulnerability in Linux kernel, published on 11 Sep 2019. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
drivers/gpu/drm/radeon/radeon_display.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value, leading to a NULL pointer dereference. NOTE: A third-party software maintainer states that the work queue allocation is happening during device initialization, which for a graphics card occurs during boot. It is not attacker controllable and OOM at that time is highly unlikely
Weakness: CWE-476
