ODP_ZEROBASED : ODP_NOT_NEEDED);\n\n* The code modified by this patch is guarded by IS_ERR(trans_private),\n where trans_private is assigned as per the previous point in this analysis.\n\n The only implementation of get_mr that I could locate is rds_ib_get_mr()\n which can return an ERR_PTR if the conn (4th) argument is NULL.\n\n* ret is set to PTR_ERR(trans_private).\n rds_ib_get_mr can return ERR_PTR(-ENODEV) if the conn (4th) argument is NULL.\n Thus ret may be -ENODEV in which case the code in question will execute.\n\nConclusion:\n* cp may be NULL at the point where this patch adds a check;\n this patch does seem to address a possible bug" } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo":
