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