Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel contains a flaw within the DRM subsystem where the
drm copy field() function may attempt to copy a NULL pointer. This occurs when a driver has a bug and fails to set required fields within the struct drm driver, leading to a kernel error when drm copy field() attempts to copy these unset fields to user space via the DRM IOCTL VERSION ioctl. The issue results in an internal error and a kernel oops. The technical details indicate a data abort and a null pointer dereference within the pi strlen function, called from drm copy field().Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
