Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue is related to the use of memory after it has been freed in the vgem gem dumb create function of the Linux kernel. This can be exploited to allow an attacker to execute arbitrary code. The root cause is that the ioctl$DRM IOCTL MODE DESTROY DUMB can decrease the refcount of drm vgem gem object (created in vgem gem dumb create) concurrently, and vgem gem dumb create will access the freed drm vgem gem object.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
