Detailsinfo

A vulnerability was found in Linux Kernel 5.2.14 (Operating System). It has been rated as problematic. This issue affects an unknown code of the file drivers/gpu/drm/radeon/radeon_display.c. The manipulation of the argument alloc_workqueue as part of a Return Value leads to a null pointer dereference vulnerability. Using CWE to declare the problem leads to CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. Impacted is availability. The summary by CVE is:

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

The weakness was disclosed 09/11/2019. The identification of this vulnerability is CVE-2019-16230 since 09/11/2019. The exploitation is known to be easy. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Technical details are known, but no exploit is available.

The real existence of this vulnerability is still doubted at the moment.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.

The entries VDB-140765, VDB-140890, VDB-141092 and VDB-141232 are pretty similar. If you want to get the best quality for vulnerability data then you always have to consider VulDB.
