  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/xe: fix NPD in bo_meminfo()\n\nWhen a buffer object is purged, its ttm.resource is set to NULL via the\nTTM pipeline gutting flow. However, the BO remains in the client's\nobject list until userspace explicitly closes the GEM handle. If memory\nstats are queried during this time, accessing bo-\u003ettm.resource-\u003emem_type\nwill result in a NULL pointer dereference.\n\nFix this by safely skipping purged BOs in bo_meminfo, as they no longer\nconsume any memory.\n\nUser is getting NPD on device resume, and possible theory is that in\nbo_move(), if we need to evict something to SYSTEM to save the CCS state,\nbut the BO is marked as dontneed, this won't trigger a move but will\nnuke the pages, leaving us with a NULL bo resource. And the meminfo()\ndoesn't look ready to handle a NULL resource.\n\nv2 (Sashiko):\n - There could potentially be other cases where we might end up with a\n   NULL resource, so make this a general NULL check for now.\n\n(cherry picked from commit c9a8e7daa0afe3161111e27fd92176e608c7f186)",
