| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The current implementation of the fpga region in the Linux kernel assumes that the low-level module registers a driver for the parent device and uses its owner pointer to take the module's refcount. This approach can lead to a null pointer dereference while attempting to get the region during programming if the parent device does not have a driver. To address this problem, a module owner pointer is added to the fpga region struct and used to take the module's refcount. The functions for registering a region are modified to take an additional owner module parameter and renamed to avoid conflicts.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
