has been resolved:\n\nspi: fix statistics allocation\n\nThe controller per-cpu statistics is not allocated until after the\ncontroller has been registered with driver core, which leaves a window\nwhere accessing the sysfs attributes can trigger a NULL-pointer\ndereference.\n\nFix this by moving the statistics allocation to controller allocation\nwhile tying its lifetime to that of the controller (rather than using\nimplicit devres)." } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo":
