Summary: Missing memset lets setversion ioctl corrupt memory.
Product: DRI
Version: unspecified
Platform: PC
OS/Version: Linux
Status: NEW
Severity: critical
Priority: P2
Component: DRM modules
AssignedTo: [email protected]
ReportedBy: [EMAIL PROTECTED]
drm_setversion() calls the driver specific version() function passing a pointer
to a local structure. The driver version function copies data to memory pointed
to by the name, date and desc structure elements if these are not NULL.
Since they are uninitialized and the structure lives on the stack these pointers
point to random addresses.
Bug found in 2.6.11 RC.
