The segment list is then DMA'ed by\nthe FW and the length of the DMA is returned by FW.  The driver then\ncopies this DMA'ed segment list to info->dest_buf.\n\nIn some cases, this DMA length may exceed the info->dest_buf length\nand cause the above BUG condition.  Fix it by capping the copy\nlength to not exceed the length of info->dest_buf.  The extra\nDMA data contains no useful information.\n\nThis code path is shared for the HWRM_DBG_COREDUMP_LIST and the\nHWRM_DBG_COREDUMP_RETRIEVE FW commands.  The buffering is different\nfor these 2 FW commands.  To simplify the logic, we need to move\nthe line to adjust the buffer length for HWRM_DBG_COREDUMP_RETRIEVE\nup, so that the new check to cap the copy length will work for both\ncommands.","state":0,"publishedAt":"2025-05-20T15:21:43.278+00:00","modifiedAt":"2026-10-15T21:52:02.73+00:00","affected":[{"ecosystem":"Vendor
