  "details": "In the Linux kernel, the following vulnerability has been resolved:  drm/gpusvm: publish dpagemap early to avoid device mapping leak on error  drm_gpusvm_get_pages() only stored the local dpagemap into svm_pages-\u003edpagemap on the success path. If a later page failed (e.g. -EOPNOTSUPP when ctx-\u003eallow_mixed is false) and jumped to err_unmap, svm_pages-\u003edpagemap was still NULL, so __drm_gpusvm_unmap_pages() skipped device_unmap() and leaked the device mappings already created.  Assign svm_pages-\u003edpagemap when the first device page is mapped so the err_unmap path can device_unmap() those mappings.  This issue was found by Sashiko AI review.",
