| 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 issue occurs when a kernel module is unbound but the pin resources were not entirely freed, and the kernel module is again bound. In this state, the pin properties would not be updated, and the prop pointer still points to the kernel module memory of the kernel module which was deallocated on the unbind. If the pin dump is invoked in this state, the result is a kernel crash. The crash is prevented by storing persistent pin properties in the dpll subsystem and copying the content from the kernel module when the pin is allocated.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
